disallow escape backspace ([\b])

📖 Rule Details

This rule reports [\b].
The word boundaries (\b) and the escape backspace ([\b]) are indistinguishable at a glance. This rule does not allow backspace ([\b]). Use unicode escapes (\u0008) instead.

/* eslint regexp/no-escape-backspace: "error" */

/* ✓ GOOD */
var foo = /\b/;
var foo = /\u0008/;
var foo = /\cH/;
var foo = /\x08/;

/* ✗ BAD */
var foo = /[\b]/;

🔧 Options

Nothing.
