Question

I am reading a tutorial and keep getting stuck on the first line of code, I know “new” in php is to make an object, but this tutorial has nothing to do with that. please help

  var img = new Image();

the tutorial is here:

Ok, I found the W3 definition of the predefined javascript object Image(): http://www.w3schools.com/jsref/dom_obj_image.asp

Answer 1

Actually, in JavaScript new is used when making objects too, just like PHP.

As you can guess, therefore, that line of code simply instantiates an Image object and assigns it to the img variable.
