Benchmark: string replace comparison

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.16.6/lodash.min.js"></script>

Script Preparation code:

var string = "I want to {replace} text {inside} (all) curly (brackets)";

var tokens = {
  "replace": "replaced",
  "other_token": "other_token_replaced",
  "token": "token_replaced",
  "inside": "inside_replaced",
  "all": "all_replaced"
};

Tests:

newRegExp obj for all tokens
for (token in tokens) { if (tokens.hasOwnProperty(token)) { string = string.replace(new RegExp('{' + token + '}', 'gi'), tokens[token]); } }
one regExp for all tokens
var r = new RegExp('\{([^\{\}]+)\}', 'g'); var handleMatched = function(match, group) { return tokens[group]; }; // Replace each token in the string with it's corresponding value for (token in tokens) { if (tokens.hasOwnProperty(token)) { string = string.replace(r, handleMatched); } }
iterating string
var lastLocation; for (token in tokens) { while ((lastLocation = string.indexOf('{' + token + '}', lastLocation)) !== -1) { string = string.replace('{' + token + '}', tokens[token]); }
reduce iterating
string = Object.keys(tokens).reduce(function(string, token) { return string.replace('{' + token + '}', tokens[token]); }, string);
same test as test 3
var lastLocation; for (token in tokens) { if (tokens.hasOwnProperty(token)) { while ((lastLocation = string.indexOf('{' + token + '}', lastLocation)) !== -1) { string = string.replace('{' + token + '}', tokens[token]); } } }
lodash reduce iterating
string = _.reduce(Object.keys(tokens), function(string, token) { return string.replace('{' + token + '}', tokens[token]); }, string);
