regexp/prefer-named-capture-group

enforce using named capture groups

📖 Rule Details

This rule reports capturing groups without a name.

This rule is inspired by the prefer-named-capture-group rule. The positions of reports are improved over the core rule and arguments of new RegExp() are also checked.

/* eslint regexp/prefer-named-capture-group: "error" */

/* ✓ GOOD */
var foo = /(?<foo>ba+r)/;
var foo = /\b(?:foo)+\b/;

/* ✗ BAD */
var foo = /\b(foo)+\b/;

🔧 Options

Nothing.
