Es5 and es6 belong to the JavaScript language. JavaScript is a high-level scripting language belonging to the network, which is composed of ECMAScript, DOM and BOM, while es5 and es6 are two versions of ECMAScript, which are used to provide syntax, types, basic objects, and so on of the JS language.

The operating environment of this tutorial: windows7 system, ECMAScript version 6, Dell G3 computer.

Es5 and es6 belong to the JavaScript language.

JavaScript (abbreviated as "JS") is a lightweight object-oriented programming language, which can be used not only in the browser to control page interaction, but also in the server as the background of the website (with the help of Node.js), so JavaScript is a full-stack programming language.

JavaScript is a high-level scripting language belonging to the network, which has been widely used in Web application development. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect. Usually JavaScript scripts implement their own functions by embedding them in HTML.

JavaScript consists of three core parts: ECMAScript,DOM (document object model) and BOM (browser object model).

ECMAScript: the core part of the language that describes the syntax and basic objects of the language.

Document object Model (Document Object Model,DOM): a web document operation standard that describes the methods and interfaces for dealing with web content.

Browser object Model (BOM): the basis of client and browser window operations, describing the methods and interfaces for interacting with browsers.

ECMAScript

ECMA-262 does not refer to the web browser and specifies the components of the language, including syntax, type, language, keywords, reserved words, operators, and objects.

ECMAScript is the description of the language in which the standard defines all aspects of content.

Compatibility of ECMAScript:

Supports all "types, values, objects, properties, functions, and program syntax and semantics" described by ECMA-262.

The Unicode character standard is supported.

Add more "types, values, objects, attributes, functions" that are not described by ECMA-262. The new features in western Zhejiang described by ECMA-262 mainly refer to new objects and new properties of objects that are not specified in the standard.

Support the syntax of programs and regular expressions that are not defined in ECMA-262. That is, you can modify and extend the built-in regular expression syntax.
