🔥 Want to strengthen your core JavaScript skills and master ES6?
I would personally recommend this awesome ES6 course by Wes Bos.

I failed to find an active maintainer. See linter-jshint for an alternative. However, I would strongly recommend trying out ESLint (Atom plugin) instead. It's just so much better than JSHint. XO (Atom plugin), which is an ESLint wrapper with sensible defaults, is also a good choice.

JSHint

Validate JavaScript with JSHint

Install

$ apm install jshint

Or Settings → Install → Search for jshint (install Jshint, not Atom Jshint)

Features

• Validates in realtime.
• Line and line number turns red on error.
• Hover over the line number to see the errors.
• Displays the error from the current line or the first error in the statusbar; clicking the statusbar message moves the cursor to the error.
• Reads your .jshintrc config and jshintConfig in package.json using the same logic as JSHint.
• Option to only validate on save.
• Command Jshint: Lint to manually lint.
• Command Jshint: Go To Next Error to move the cursor to the next error in the current editor.
• Command Jshint: Go To Error to move the cursor to the error displayed in the statusbar.
• Supports React JSX. (must be enabled in Settings)
