What is html5?

• It supports multimedia elements,

• It has the following functions: access user geolocation,

#What is javascript?

Javascript is a dynamic scripting and interpreted programming language used to build web page behavior. Javascript is a lightweight, prototyping and versatile language.

Javascript is an interpreted high-level programming language with object-oriented features.

Programs used in Javascript language are called scripts. They can be written in the HTML page or automatically executed when the page loads. The language is designed to be embedded in Internet Explorer, Netscape, and many other web browsers.

Some advantages of Javascript:

• It has very little interaction with the server

• If the user misses entering some information, It will provide immediate feedback to the user/visitor.

• Browser detection, cookies, controlling browsers and verification forms, etc.

The difference between html5 and javascript

1. HTML5 is the markup language of the Internet, while Javascript is a dynamic script and Interpreted programming language.

2. HTML5 is used to create the basic structure and display content in the WWW; while Javascript is the basic component of HTML5, Javascript is used to define interactive elements of web pages to help attract users.

HTML5 is broadly synonymous with the discipline of front-end development. It includes three important parts: HTML5, CSS3 and JavaScript. It is a collective name for applications running on browsers. Such as PC websites, management systems, mobile web applications (WebApps), hybrid applications (HybridApps), WeChat official accounts, mini programs, mini games, data visualization, etc.

As can be seen from the above, the new APIs in HTML5 are inseparable from JavaScript. JavaScript is The core of front-end development is that you cannot develop front-end if you only learn HTML5, or only learn HTML5 tags. In other words, it is not comprehensive in the first place, because HTML5 includes JavaScript Api.

3. Compared with Javascript, HTML5 is more secure and scalable because the application code will be written on the server side, while the Javascript code will be written in the database called an Ajax application.

4. Compared with HTML5, Javascript is faster because it does not need to communicate with the Server and wait for a response from it, while HTML5 needs to communicate within it and wait for its response.
