Benchmark: instanceof vs typeof vs Object.prototype.toString.call

Script Preparation code:

var obj = {a:2};

Tests:

instanceof
obj instanceof Object
typeof
typeof obj === 'object'
typeof no function
typeof obj === 'object' && typeof obj !== 'function'
Object.prototype.toString.call ==
"[object Object]" == Object.prototype.toString.call(obj)
Object.prototype.toString.call ===
"[object Object]" === Object.prototype.toString.call(obj)
