10 Best Tools for Developing JavaScript-JS Tutorial-php.cn

If a worker wants to do his job well, he must first sharpen his tools. As a qualified front-end engineer, how can he improve his efficiency while writing code to the extreme? This depends on what development tool we choose. Today I will introduce to you the 10 best tools for developing JavaScript. These tools are highly recommended by many peers. Today I will summarize them for you.

JavaScript, a language supported by all major browsers, is the workhorse of developing browser-based web applications and receives attention from many developers almost every year. Naturally, an ecosystem of frameworks and libraries has evolved around JavaScript to simplify and enhance the development of JavaScript applications.

These tools provide functionality from event handling to code reduction and data rendering. The following is a summary of the most essential technologies in a JavaScript developer's toolkit for developing browser-based web applications.

Angular

Angular, formerly known as AngularJS developed by Google, is a single framework for mobile and desktop web development. To create native-like progressive web applications, Angular provides dependency injection for assembling the application's data services, as well as HTML templates for composite components.

The Angular project quick start page allows developers to easily start using Angular.

Angular Features

The September 2016 version 2 of Angular featured a rewrite based on TypeScript (Microsoft’s typed superset of JavaScript) to handle the architecture in the initial release of Angular performance limitations.

Now, developers are waiting for Angular 5, which is expected to be released on October 23rd (there is no version 3 or 4). Its anticipated features include:

For caching applications in the browser to enhance the ease of building progressive web applications.

Build an optimizer to make applications smaller by removing unnecessary code.

Make Material Design components compatible with server-side rendering.

Angular 6, expected to be released five to six months later than Angular 5, will focus on the same themes as Angular 5: ease of use, smaller size and performance. Angular itself has a strong ecosystem with four databases and support in IDEs such as JetBrains IntelliJ Idea.

Aurelia

Composed of focused modules, Aurelia is a client-side framework for mobile, desktop and web applications developed by Blue Spire. It enables fast rendering and "efficient" memory usage.

Where to download Aurelia?

You can download Aurelia from GitHub.

Function of Aurelia

Aurelia has modules for handling metadata, dependency injection, binding, templates and routing. Aurelia integrates web components and provides two-way

data binding

to objects. Most Aurelia code is written in pure JavaScript. Other features include:An HTML compiler for building custom elements and adding attributes to elements.

Support dynamic loading.

Dependency injection container for unit testing that can build coupled code.

Aurelia CLI that provides options to create new projects, requires Node 4 or higher, NPM 3 and Git installed.

Integration with the Polymer library for building reusable web components.

template engine

, bindable inheritance is supported when used for component inheritance.

Backbone.js

Backbone.js, also known as Backbone, provides structures for JavaScript-heavy applications. It has models with key-value bindings and custom events, which are a collection of APIs that support enumerable functions and declarative event handling views.

Where to download Backbone.js?

You can download development versions and product release versions from the Backbone project website.

Backbone.js functions

Data in Backbone.js is represented using models that can be created, verified, destroyed, and saved to the server. These models are connected to the application through a RESTful JSON interface. When using Backbone.js, a model fires a change event when a UI action prompts it to change its properties. Views that display model state are notified of this change and re-render them.

Ember.js

Ember.js is a framework that emphasizes high efficiency out of the box. It has integrated templates, called handlebars, designed to reduce the amount of code you write; these templates automatically update when data changes.

Where to get Ember.js

You can enter npm install -g ember-cli@2.15 in NPM to install Ember.js.

Features of Ember.js

Features of Ember.js include:

Focused on APIs that simplify development.

Focus on common styles that let developers specialize applications.

The Ember.js 3.0 stable version will be released on February 12, after the beta version was released on January 1, 2018. APIs deprecated in version 2.x are still supported and will be cleared in Ember.js 3.x. An add-on should support the Ember.js 2x API in 3.x lines of code.

Ext JS

Unlike other well-known JavaScript frameworks, Sencha’s Ext JS is not open source; it is a commercial product. It is used to build data-intensive cross-platform web applications for enterprises that require multiple form factors.

Where to download Ext JS?

The Ext JS software can be downloaded from Sencha’s Ext JS page.

Features of Ext JS

Ext JS framework provides many components such as data grid and calendar. Ext JS can be used with tools like Sencha Architect, for drag-and-drop HTML5 application development, and Sencha Themer, for application styling.

Ext JS builders are considering how to use the Ext JS architecture to perform long-term tasks. Sencha planned to release Ext JS 7 late this year or early next, but those plans are now on hold due to Sencha's acquisition of Idera. Discussions have been held on the feasibility of providing compliance with the latest ECMAScript standards and using the NPM package manager and Webpack module binder.

jQuery

The API of JavaScript’s jQuery library provides functions such as operating HTML documents, event handling, and animation. The jQuery library is managed by the JS Foundation and was first released in August 2006.

Where to download jQuery?

jQuery can be downloaded from the jQuery project website.

Features of jQuery

jQuery is not a framework for building applications, but it provides a basic API that makes it easy to manipulate the DOM in the browser. jQuery can also be used with application building tools such as Angular and React/Redux.

The jQuery team is now releasing roughly two versions a year, with only a few minor releases between now and mid-2018. In addition to this, jQuery 4.0 and subsequent versions require a complete rewrite using "next generation" JavaScript, which requires updates to the build system. There are also the following plans in jQuery 4 and subsequent versions:

Rewrite jQuery's speed framework and track performance regressions

The newly designed event model will discard special event hooks to avoid using jquery. A wrapper for the Event class

Pay for new native options like passive event listeners

Meteor

Meteor (aka Meteor.js ) is a JavaScript framework that enables faster development of web, mobile, and desktop applications using less code. Developers can use JavaScript in all environments, including on application servers, web browsers, and mobile devices.

Where to download Meteor

Meteor software can be downloaded from the Meteor project website.

Features of Meteor

The Meteor platform, also known as Meteor.js, includes technology for building reactive applications with connected clients, build tools, and a range of features from Node.js and JavaScript community packages. With Meteor, the server sends data through the device instead of HTML and then renders it on the client.

Meteor 1.6 is the next release number, which focuses on upgrading to Node.js 8, which will allow Meteor to better take advantage of ECMAScript capabilities on the server, thereby improving build performance.

Polymer

Google's Polymer JavaScript library is designed to enable developers to take full advantage of web components, providing the possibility for reusable custom elements to interact with built-in browser elements.

Where to download Polymer?

You can install Polymer from the Bower package manager.

Features of Polymer

Polymer version 2.0, released in May, improves interoperability by removing Polymer.dom used in DOM operations. This makes it easier to use Polymer components when using other libraries and frameworks.
Other features in Polymer 2.0 include:

Improvements to the data system to improve debugging and passing of data through and between elements.

ECMASript 2015 classes and standard custom elements. Methods in Polymer version 1 are used to define elements instead of using Plymer's factory methods. But factory methods are still supported through the compatibility layer.

Simpler array processing.

Upcoming release is Polymer 3.0, which is currently in preview and features include Bower and HTML import, NPM and ECMAScript 15 modules. Bower and HTML imports functionality is suitable for HTML import-based workflows. However, they place Polymer outside the mainstream of web development and make it difficult for people to use other frameworks or build tools.

React

The React library used by Facebook to build user interfaces, providing component-based declarative views , using JavaScript Write component logic. The React library, also known as React.js, does not support models and controllers, but these functions can be improved through other related projects. Where to download React

React can be downloaded from the React project website.

React Features

You can use React’s JSX syntax to describe the user interface. JSX allows mixing JavaScript and HTML in a single component. It is converted to pure JavaScript during the build process.

In order to improve performance, React rewrote the architecture in the recent release React 16, called Fiber. The main feature of this update is a focus on asynchronous rendering in order to handle large components. However, React itself does not yet support asynchronous rendering, which will be implemented in the React 16.x version line.

Other improvements in React 16 include:

Provides component stack tracing, making debugging easier.

You can directly return a string or array in the component's rendering method (render).

New faster, stream-based server-side rendering.

Closer to the performance of native applications.

After some organizations such as the Apache Software Foundation objected to its licensing terms, React revised its new license based on BSD+MIT Patents. Apache is concerned that licensing based on BSD + Patents will make the software no longer a "universal donor" for downstream projects.

Vue.js

Vue.js is one of React’s competitors that claims faster rendering speeds. The core library focuses on the view layer, and the framework is primarily designed for incremental implementation.

Where to download Vue.js?

Vue.js software can be downloaded from the Vue.js project website.

Features of Vue.js

Declarative rendering is the key in Vue.js, using template syntax to render data into the DOM. The Vue.js component system is an abstraction that supports large applications composed of self-contained development and reusable modules. A component in Vue.js is essentially a Vue instance with predefined options.

Vue.js 2.5 will arrive in October 2017, with better integration of TypeScript features. Plans for later versions of Vue.js include:

Making it easier for TypeScript users to start new projects in Vue.js

A reactive system using the proxy rewrite framework

Support WebAssembly portable code format

The ability to absorb more functions of Web components
