Benchmark: Benchmark 2: Expressions / Placeholders

Script Preparation code:

var expression = 'return a === b';
var cachedExprFn = new Function('a', 'b', expression);

Tests:

Test 1 — eval (expression):
var a = "returned", b = "returned"; eval('a === b');
Test 2 — new Function (expression, no cache):
new Function('a', 'b', 'return a === b')("returned", "returned");
Test 3 — new Function (expression, cached):
cachedExprFn("returned", "returned");
Test 4 — script tag (expression):
var s = document.createElement('script'); s.textContent = '"returned" === "returned"'; document.head.appendChild(s); document.head.removeChild(s);
