Summary

RegExp.escape is a static method that takes a string and returns an escaped version that may be used as a pattern inside a regular expression. For example, copied from the proposal explainer: ``` const str = prompt("Please enter a string"); const escaped = RegExp.escape(str); const re = new RegExp(escaped, 'g'); // handles reg exp special tokens with the replacement. console.log(ourLongText.replace(re)); ```

It seems like shipped in 136; should we update the milestone if so?
