# Quickstart JSLint in CodeMirror
1. Download and save [`jslint.mjs`](https://www.jslint.com/jslint.mjs), [`jslint_wrapper_codemirror.js`](https://www.jslint.com/jslint_wrapper_codemirror.js) to file.

2. Edit, save, and serve example html-file below:
```html


CodeMirror: JSLint Demo






body {
background: #bbb;
color: #333;
font-family: sans-serif;
margin: 20px;
}
.JSLINT_.JSLINT_REPORT_ {
margin-top: 20px;
}
#editor1 {
height: 300px;
width: 100%;
}

CodeMirror: JSLint Demo



This demo will auto-lint the code below, and auto-generate a report as you type.

console.log('hello world');

window.addEventListener("load", function () {
let editor = window.CodeMirror.fromTextArea(document.getElementById(
"editor1"
), {
gutters: [
"CodeMirror-lint-markers"
],
indentUnit: 4,
lineNumbers: true,
lint: {
lintOnChange: true, // Enable auto-lint.
options: {
// browser: true,
// node: true
globals: [
// "caches",
// "indexedDb"
]
}
},
mode: "javascript"
});

// Initialize event-handling before linter is run.

editor.on("lintJslintBefore", function (/* options */) {
// options.browser = true;
// options.node = true;
// options.globals = [
// "caches",
// "indexedDb"
// ];
return;
});

// Initialize event-handling after linter is run.

editor.on("lintJslintAfter", function (options) {

// Generate jslint-report from options.result.

document.querySelector(
".JSLINT_REPORT_"
).innerHTML = window.jslint.jslint_report(options.result);
});

// Manually trigger linter.

editor.performLint();
});

```

# Quickstart JSLint in Vim
1. Download and save [`jslint.mjs`](https://www.jslint.com/jslint.mjs), [`jslint_wrapper_vim.vim`](https://www.jslint.com/jslint_wrapper_vim.vim) to directory `~/.vim/`
2. Add vim-command `:source ~/.vim/jslint_wrapper_vim.vim` to file `~/.vimrc`
3. Vim can now jslint files (via nodejs):
- with vim-command `:SaveAndJslint`
- with vim-key-combo ` `
- screenshot

# Quickstart JSLint in VSCode
1. In VSCode, search and install extension [`vscode-jslint`](https://marketplace.visualstudio.com/items?itemName=jslint.vscode-jslint)
2. In VSCode, while editing a javascript file:
- right-click context-menu and select `[JSLint - Lint File]`
- or use key-binding `[Ctrl + Shift + J], [L]`
- or use key-binding `[ Cmd + Shift + J], [L]` for Mac
- screenshot

# Documentation

- [jslint.mjs](jslint.mjs) contains the jslint function. It parses and analyzes a source file, returning an object with information about the file. It can also take an object that sets options.

- [index.html](index.html) runs the jslint.mjs function in a web page.

JSLint can be run anywhere that JavaScript (or Java) can run.

The place to express yourself in programming is in the quality of your ideas and
the efficiency of their execution. The role of style in programming is the same
as in literature: It makes for better reading. A great writer doesn't express
herself by putting the spaces before her commas instead of after, or by putting
extra spaces inside her parentheses. A great writer will slavishly conform to
some rules of style, and that in no way constrains her power to express herself
creatively. See for example William Strunk's The Elements of Style
[https://www.crockford.com/style.html].

This applies to programming as well. Conforming to a consistent style improves
readability, and frees you to express yourself in ways that matter. JSLint here
plays the part of a stern but benevolent editor, helping you to get the style
right so that you can focus your creative energy where it is most needed.
