[javascript] How to loop through an array containing objects and access their properties

It's really simple using the forEach method since ES5+. You can directly change each property of each object in your array.

myArray.forEach(function (arrayElem){ 
  arrayElem = newPropertyValue;
});

If you want to access a specific property on each object:

myArray.forEach(function (arrayElem){ 
      arrayElem.nameOfYourProperty = newPropertyValue;
    });
