Why use a token variable and not just push the i to the new array?

Why use:

for (let i = 0; i < num; i++) { let token = new Token(i, this); tokens.push(token); }

and not just:

for (i = 0; i < num; i++) { tokens.push(i); }

tokens is an array of token objects. A token has owner, id, dropped and columnLocation properties. Try adding console.log(tokens) to createTokens(num) to see the difference.

The first code creates a token object and adds that to the array. For i = 0 you have:

0: Token {owner: Player, id: "token-0-1", dropped: false, columnLocation: 0}

i is an integer. The second code (modified to let i = 0) just adds the integer. For i = 0 you have:

0: 0
