How to set up Sublime to support JavaScript development

Sublime is a very popular text editor, which is widely used in code programming, website development and other fields. For front-end developers, setting up Sublime can better support JavaScript development and improve work efficiency. This article mainly introduces how to set up Sublime to support JavaScript development.

1. Install Sublime plug-in
   Sublime plug-in is a way to enhance the functionality of Sublime. For JavaScript development, we can extend Sublime by installing the following plugins:

• Package Control: This is a must-have plugin for Sublime, which allows you to install and manage other Sublime plugins.
• JavaScript Snippets: This plug-in provides some JavaScript templates and code snippets to quickly write common JavaScript codes.
• JavaScript Next: This plugin provides support for new features of ES6 and ES7, including arrow functions, destructuring, Promise, etc.
• Brackethighlighter: This plug-in can highlight matching brackets in the editor, making code reading easier.

The method to install these plug-ins is very simple: open Sublime and enter the following command in the console:

import urllib.request,os; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.proxyHandler()) ); open(os.path.join(ipp, pf), 'wb').write(urllib.request.urlopen( 'http://sublime.wbond.net/' + pf.replace(' ','%20')).read())

This will install Package Control. Next, press Ctrl Shift P in Sublime, open the command panel, enter "Install Package" and select the item, then enter different plug-in names in the search box to install.

2. Configuring Sublime
   After installing the plug-in, you need to configure Sublime as a development environment that supports JavaScript.

First, you need to turn on JavaScript syntax highlighting. Select View > Syntax > JavaScript in the Sublime menu bar. This will activate JavaScript syntax highlighting for .js files.

Then, you need to configure the behavior of the Tab key in Sublime so that code is automatically generated when the Tab key is pressed. In Preferences > Settings, open the User Settings file and add the following settings:

{
    "tab_size": 2,
    "translate_tabs_to_spaces": true,
    "auto_indent": true,
    "default_line_ending": "unix",
    "rulers": [80],
    "draw_white_space": "all",
    "trim_trailing_white_space_on_save": true
}

These configurations will cause the Tab key to automatically indent when editing code, use two spaces as the indentation symbol, and save Remove trailing spaces from the file.

In addition, you can add syntax checking to your code in Sublime. By installing the JSHint and SublimeLinter plugins, you can display syntax errors and warnings for your code in the editor. After installing the JSHint plug-in, SublimeLinter will automatically take effect.

3. Using Sublime for JavaScript development
   After setting up Sublime’s development environment, we can start writing JavaScript code in Sublime. Use the shortcut key Ctrl N to create a new file and enter the following code into the file:

var person = {
    name: 'John',
    age: 30,
    greet: function() {
        console.log('My name is ' + this.name + ', and I am ' + this.age + ' years old.');
    }
};

person.greet();

This is a simple JavaScript object declaration that defines a person object and a greet method. In Sublime, press Ctrl B to run the code and see the results.

In addition, Sublime also supports code snippets, which can improve the speed and quality of code writing when editing. The JavaScript Snippets plug-in already provides multiple code snippets. By entering the snippet name, the corresponding code can be quickly generated. Press Ctrl Shift P to open the command panel, enter "Snippet", select the required code fragment, and the code fragment will be automatically generated.

To sum up, by setting Sublime, it can better support JavaScript development. Using Sublime's syntax highlighting, tab key shortcuts and syntax checking can improve the speed and quality of code writing, bringing a more efficient programming experience to JavaScript development.
