of a scope is a function, and that scope is a lexical scope (same as JavaScript).So whenever a function call is encountered, we need to create a new evaluation environment and make it the same environment as the parent environment of this new evaluation environment (if you don't understand why, search for lexical scopes yourself). So when we look for variables anywhere, we should look up the environment chain (scope chain) until we find them. Throws

In daily website development and web application development, we often need to effectively call functions related to date and time formats for Javascript processing, javascript contains some of the most basic built-in processing methods. Of course, if you have time, you can develop and compile the required methods by yourself. However, it is certainly a better way to effectively use the

enrich your JavaScript class libraryEvery good developer will form its own class library, and as a Java developer, we will also write a bunch of tool classes to simplify our development efforts. But as a full station siege lion, not only to understand the formation of Java class Library,

class in ES6 is equivalent to a constructor in es5, and if no constructor attribute is defined, an empty constructor is added by default;3,es5 , inheritance is a subclass that first creates its own instance object this, and then invokes the method of the parent class through Parent.call (this) or parent.apply (this);es6 , inheritance is The parent class first cr
