JavaScript common function toolset: lao-utils_javascript skills

In my work, I often use some methods frequently, or do type judgment, data conversion, etc. For convenience, some functions are encapsulated into functions and organized into the tool set lao-utils

npm install lao-utils --save

AMD/CMD, browser environment

Introduce source code files in the dist directory

Function

uuid() generates a uuid string (pseudo-guid)

merge(a,b,c,...rest) Merge objects
eg: laoUtils.merge({a:1},{b:2},{b:3,c:3}); //{a:1,b:3,c:3}

arrayOf(a,b,c,...rest) Convert a set of values ​​to an array (convert parameters to an array)
eg: laoUtils.arrayOf(1,2,3); //[1,2,3]

includes(arr,value) Whether the array arr contains the given value value.
eg: laoUtils.includes([1,2,3],3); //true
