indexOf vs Regex (grunt.template)

Benchmark created by John Doe on October 14, 2014

Setup

var template = '{%= foo %}';
    
    var delimiters = {};
    
    var opener = '{%';
    var closer = '%}';
    
    var a = opener.replace(/(.)/g, '\\$1');
    var b = '([\\s\\S]+?)' + closer.replace(/(.)/g, '\\$1');
    
    delimiters.lodash = {
      evaluate: new RegExp(a + b, 'g'),
      interpolate: new RegExp(a + '=' + b, 'g'),
      escape: new RegExp(a + '-' + b, 'g')
    };
    
    var regexOr = new RegExp(delimiters.lodash.evaluate.source + '|' +
                           delimiters.lodash.interpolate.source + '|' +
                           delimiters.lodash.escape.source);
    var regexGroups = new RegExp('(' + delimiters.lodash.evaluate.source + ')|(' +
                           delimiters.lodash.interpolate.source + ')|(' +
                           delimiters.lodash.escape.source + ')');
    var regexGroupsNonCapturing = new RegExp('(?:' + delimiters.lodash.evaluate.source + ')|(?:' +
                           delimiters.lodash.interpolate.source + ')|(?:' +
                           delimiters.lodash.escape.source + ')');

Test runner

template.indexOf(opener) >= 0

delimiters.lodash.evaluate.test(template) || delimiters.lodash.interpolate.test(template) || delimiters.lodash.escape.test(template)

regexOr.test(template)

regexGroups.test(template)

regexGroupsNonCapturing.test(template)
