This article mainly explains "what is ES6". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is ES6".

ESMAScript is a programming language that can perform calculations in the host environment and manipulate the basic objects of the calculated objects. Compared with other versions of standards, ES6 syntax is more concise and more powerful, which greatly improves the development efficiency and code security. At present, a variety of environments and popular frameworks support the ES6 standard, and you can quickly upgrade your skills when learning open source frameworks. In addition, with the application of ES6, the front-end and back-end syntax tends to be unified, and the front-end differentiation is greatly reduced. In line with the current development trend of the big front end. It is a technology that front-end development engineers must master at present.

In the ES6 book, many new syntax features have been added, including familiar Promise, unheard of Proxy proxy and Reflection reflection; compatible let, const, indefinite parameters, expansion operators and other functions that can be implemented in old browsers through translators (Transpiler), as well as forward-compatible tail call optimization. An in-depth understanding of the features of ES6 is critical for all JavaScript developers, and the language features introduced in ES6 will become mainstream features of JavaScript applications in the foreseeable future.

What knowledge points do you need to master to learn ES6?

1. Let and const commands to define variables and constants.

2. Deconstruct the assignment and extract the corresponding value from the array or object.

3. ES6 extension, string expansion, numerical expansion, array expansion, function expansion, object expansion.

4. Symbol and Symbol attribute, Symbol as attribute name, prevent attribute name conflict, simulate private attribute

5. Proxy and Reflect, object broker, data validation, analog two-way data binding.

6. Set and Map data structures, new Set structure with unique member values, and new Map structure with set of key-value pairs.

7. Iterator and for...of loops, traversers, allow any data structure to define the traversal interface.

8. Asynchronous programming, Generator function, Promise object, async function.

9. Class class, Class class, object creation, inheritance, static methods and properties.

10. Module is modularized and programmed with modularization idea.

Which people are suitable for learning ES6?

If you want to learn ES6, you'd better have some Web front-end development foundation and some basic knowledge of HTML/CSS/JavaScript. Secondly, you should understand the important role of ES6, have interest in or learning needs for ES6, and want to learn ES6-related knowledge systematically. Or you are currently planning to learn the mainstream front-end framework, suffering from the way ES5 is integrated, and want to improve your technical ability and job competitiveness by learning ES6 to improve work efficiency.

Thank you for your reading, the above is the content of "what is ES6", after the study of this article, I believe you have a deeper understanding of what ES6 is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
