Question

what\'s the difference between Browsers and Node? for instance:

setName.js on Node:

var setName;
setName = function (name) {
    return          


        

Answer 1

Your browser code has the window host object. Node does not have that host object. When you set this.name, you are actually setting it to the window object aka making a global variable.

window.name === this.name // true
