RegexVsSplitReplaceAll

Benchmark created by sam adams on

Description

.replace only replaces first instance of search string. to replace all we can either use a greedy regex or split (split on search and join on replacement). Which is faster tho?

Setup

var str = 'some code with "replacements"';
    var replacement = '\\"';
    var search = '"';
    var regex = new RegExp(search, 'g');

Test runner
