Question 1

How do I configure JSLint to allow bitwise operators?

Accepted Answer

Add the /*jslint bitwise*/ directive at the top of your JavaScript file. This tells JSLint to permit bitwise operations, which are otherwise flagged as warnings due to potential confusion.

Question 2

JSLint vs ESLint: which should I choose for a new project?

Accepted Answer

JSLint is ideal for teams valuing strict, opinionated standards and integrated coverage, while ESLint offers more flexibility with customizable rules and a vast plugin ecosystem. Consider your team's tolerance for rigidity and need for modern tooling.

Question 3

How to ignore a specific warning on a single line in JSLint?

Accepted Answer

Use the //jslint-ignore-line comment at the end of the line to suppress non-fatal warnings. For example, eval('1'); //jslint-ignore-line will ignore the eval warning on that line.

Question 4

Does JSLint support TypeScript or JSX files?

Accepted Answer

No, JSLint is designed for plain JavaScript and does not natively support TypeScript or JSX syntax. You would need to use transpilers or other linters for those languages.

Question 5

How to generate a V8 coverage report from npm tests with JSLint?

Accepted Answer

Use the v8_coverage_report option in shell commands or the v8CoverageReportCreate API, specifying include and exclude patterns to filter files, as detailed in the quickstart section with examples for Node.js programs.

Question 6

Can JSLint be used with React or Vue.js projects?

Accepted Answer

JSLint can lint JavaScript files in these projects, but it may not handle JSX or framework-specific patterns without custom directives or pre-processing. Integration might require additional tooling.

Question 7

How to integrate JSLint into VSCode for real-time linting?

Accepted Answer

Install the vscode-jslint extension from the marketplace, then use right-click menus or key bindings like Ctrl+Shift+J L to lint files, as described in the quickstart guide with screenshots.
