Javascript - Override console.log and keep the old function

Question

I would like to override console.log and call it on my new function.

I try something like this but I get Uncaught TypeError: Illegal invocation:

Answer 1

You are invoking the console.log function on the window object. You should instead invoke it on the console object.

console.log = function() {
  this.apply(console, arguments);
}.bind(console.log);

console.log('as');
