Benchmark: React JS vs HTML Template Dom manipulation

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js'></script>
<script type="text/html" id="raw-template">
            <div class="row">
                <div class="col-md-12 test-data">
                    <span class="{{className}}">{{label}}</span>
                </div>
            </div>
        </script>

<div id="raw-react" style="display:none;"></div>
<div id="raw-revision" style="display:none;"></div>
<div id="raw-original" style="display:none;"></div>

Script Preparation code:

function _buildData(count) {
  count = count || 1000;
  var adjectives = ["pretty", "large", "big", "small", "tall", "short", "long", "handsome", "plain", "quaint", "clean", "elegant", "easy", "angry", "crazy", "helpful", "mushy", "odd", "unsightly", "adorable", "important", "inexpensive", "cheap", "expensive", "fancy"];
  var colours = ["red", "yellow", "blue", "green", "pink", "brown", "purple", "brown", "white", "black", "orange"];
  var nouns = ["table", "chair", "house", "bbq", "desk", "car", "pony", "cookie", "sandwich", "burger", "pizza", "mouse", "keyboard"];
  var data = [];
  for (var i = 0; i < count; i++) {
    data.push({
      id: i + 1,
      label: adjectives[_random(adjectives.length)] + " " + colours[_random(colours.length)] + " " + nouns[_random(nouns.length)]
    });
  }
  return data;
}

function _random(max) {
  return Math.round(Math.random() * 1000) % max;
}

Tests:

HTML Fragment
var fragment = document.createDocumentFragment(), $raw = document.querySelector('#raw-revision'), data = _buildData(); data.forEach(function(row) { var rowDiv = document.createElement('div'); var innerDiv = document.createElement('div'); var span = document.createElement('span'); rowDiv.className = 'row'; innerDiv.className = 'col-md-12 test-data'; span.textContent = row.label; rowDiv.appendChild(innerDiv); innerDiv.appendChild(span); fragment.appendChild(rowDiv); }); $raw.appendChild(fragment); $raw.addEventListener('click', function(e) { if (e.currentTarget.className === 'span') { document.querySelector('.selected').className = ''; e.currentTarget.className = 'selected'; } });
Original DOM Manipulation Code
var data = _buildData(), template = $("#raw-template").html(), html = ""; document.getElementById("raw-original").innerHTML = ""; for (var i = 0; i < data.length; i++) { var render = template; render = render.replace("{{className}}", ""); render = render.replace("{{label}}", data[i].label); html += render; } document.getElementById("raw-original").innerHTML = html; $("#raw").on("click", ".test-data span", function() { $("#raw .selected").removeClass("selected"); $(this).addClass("selected"); });
DOM Manipulation with Templates
var data = _buildData(), template = function(obj) { return [ '<div class="col-md-12 test-data">', '< span class = "', obj.className ,'" >', obj.label,' < /span>', '</div >'].join(''); }, raw = document.getElementById("raw-original"), html = ""; raw.innerHTML = ""; var div; for (var i = 0; i < data.length; i++) { div = document.createElement('div'); div.innerHTML = template({ 'className': '', 'label': data[i].label }); raw.appendChild(div); } $(raw).on("click", ".test-data span", function() { $(".selected", raw).removeClass("selected"); $(this).addClass("selected"); });
React
var Class = React.createClass({ select: function(data) { this.props.selected = data.id; this.forceUpdate(); }, render: function() { var items = []; for (var i = 0; i < this.props.data.length; i++) { items.push(React.createElement("div", { className: "row" }, React.createElement("div", { className: "col-md-12 test-data" }, React.createElement("span", { className: this.props.selected === this.props.data[i].id ? "selected" : "", onClick: this.select.bind(null, this.props.data[i]) }, this.props.data[i].label) ) )); } return React.createElement("div", null, items); } }); var data = _buildData(); React.render(new Class({ data: data, selected: null }), document.querySelector('#raw-react'));
