Script Preparation code:
​x
 
var array = [];
for (var i=0, t=10000; i<t; i++) {
    array.push(Math.round(Math.random() * t))
}
var t=0;

Tests:

  • for let

     
    for (let i = 0; i < array.length; i++) {
      t += array[i];
    }

  • for var

     
    for (var i = 0; i < array.length; i++) {
      t += array[i];
    }
    ​

  • for let cached

     
    let len=array.length;
    for (let i = 0; i < len; i++) {
      t += array[i];
    }

  • for let cached (const)

     
    const len=array.length;
    for (let i = 0; i < len; i++) {
      t += array[i];
    }

  • for var cached

     
    var len=array.length;
    for (var i = 0; i < len; i++) {
      t += array[i];
    }

  • forEach

     
    array.forEach(function(v, i) {
      t += v;
    });
