Trouble in understanding this syntax in JavaScript?

Question

var log = (0, _lodash.memoize)(function (message) {
  console.log((0, _ansicolors.red)('WARNING:'), message);
});

I am facing difficulty in understanding the above code. This code was written in JavaScript.

my understand is that a function is passed to lodash memoize method as parameter and what that '0' is doing? i may be wrong... — Vasu

Perhaps this question will show what purpose the 0 might have. Hint: the zero could have been any value. It's the comma which has special behavior. — castletheperson

Basically the code (0, _lodash.memoize) eliminates the need to make a new instance and directly gives you the value of function rather than reference.
