Pattern: Misleading capturing group
Issue: -
This rule reports capturing groups that capture less text than their pattern might suggest.
E.g. in /a+(a*)/, (a*) will always capture 0 characters because all as are already consumed by a+. This is quite surprising behavior because a* suggests that the capturing group captures as many as as possible.
/* eslint regexp/no-misleading-capturing-group: "error" */
/* ✓ GOOD */
var foo = /a+(b*)/
/* ✗ BAD */
var foo = /a+(a*)/
var foo = /\w+(\d*)/
var foo = /^(a*).+/
