I would like to you Array.prototype.map method on an array of given length to initialise it with the objects. Note that I do not intend to any kind of loop here.

I had an idea to this as

cells = Array(numberOfCells).map(() => new Cell());

However, this does not work. Could somebody point out why and suggest a solution of a similar kind?

    `Array.from({length: numberOfCells}).map(() => new Cell());` – Tushar Apr 06 '17 at 08:34

This should work: 

cells = Array.from(numberOfCells, () => new Cell());

edit: However, @Ryan was the first to point it out in the comments
