深度JavaScript (Deep JavaScript)

Choosing a development tool based on its popularity isn’t a bad idea. Popular tools are usually more stable, and they often have more resources and community support than less popular tools. Today, I’ll introduce categories of tools and lots of names of specific tools.

根据流行程度选择开发工具不是一个坏主意。 流行的工具通常更稳定，并且与不那么流行的工具相比，它们通常具有更多的资源和社区支持。 今天，我将介绍工具类别和许多特定工具的名称。

Let’s start now…!

让我们现在开始…！

构建工具 (Build Tools)

We build the JavaScript source codes we write to what we deploy using build tools.

我们构建JavaScript源代码，并使用构建工具将这些源代码写入部署的内容。

转运器 (Transpilers)

A transpiler is a tool that compiles source code to source code. There are two transpilers that are popular in the community as follows.

编译器是将源代码编译为源代码的工具。 以下是在社区中流行的两种编译器。

• Babel is a compiler that helps you write code in the latest version of JavaScript. When your supported environments don’t support certain features natively, Babel will help you compile those features down to a supported version.

  Babel是一个编译器，可以帮助您使用最新版本JavaScript编写代码。 当您支持的环境本身不支持某些功能时，Babel将帮助您将这些功能编译为支持的版本。

• Typescript is a superset of JavaScript in addition to all the new stuff that the standard is defining, will add a static type system. Typescript has also a transpiler that converts our Typescript code (i.e. ES6 + types) to ES5 or ES3 javascript code so we can use it in today’s browsers.

  Typescript是JavaScript的超集，除了标准定义的所有新内容外，还将添加静态类型系统。 Typescript还有一个编译器，可将我们的Typescript代码(即ES6 +类型)转换为ES5或ES3 javascript代码，因此我们可以在当今的浏览器中使用它。

缩小器 (Minifiers)

A Minifiers is a tool that removes unnecessary or redundant data without affecting how the resource is processed by the browser — e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on.

Minifiers是一种工具，它可以删除不必要的数据或冗余数据，而不会影响浏览器对资源的处理方式-例如，代码注释和格式设置，删除未使用的代码，使用较短的变量和函数名称等。

There are some popular minifiers including:

有一些流行的缩小器，包括：

• UglifyJS is a JavaScript parser, minifier, compressor and beautifier toolkit.

• Terser is aJavaScript parser and mangler/compressor toolkit for ES6+.

  Terser是ES6 +JavaScript解析器和mangler / compressor工具包。

• Closure Compiler is a tool for making JavaScript download and run faster. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what’s left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.

  Closure Compiler是使JavaScript下载和运行速度更快的工具。 它不是从源语言编译为机器代码，而是从JavaScript编译为更好JavaScript。 它解析您JavaScript，对其进行分析，删除无效代码，然后重写并最大程度地减少剩下的内容。 它还检查语法，变量引用和类型，并警告常见JavaScript陷阱。

捆绑包： (Bundlers:)

A JavaScript bundler is a tool that puts your code and all its dependencies together in one JavaScript file. It also minimizes the size of output by using techniques such as tree-shaking and perform compilation steps such as transpiling and minification while bundling.

JavaScript捆绑程序是一种工具，可将您的代码及其所有依赖项放到一个JavaScript文件中。 它还通过使用诸如摇树之类的技术来最小化输出的大小，并在捆绑时执行诸如编译和最小化之类的编译步骤。
