I have difficulty understanding a javascript code here.
Can I get some help?
let size = 8;
let board = “”;
for (let y = 0; y < size; y++) {
for (let x = 0; x < size; x++) {
if ((x + y) % 2 == 0) {
board += " ";
} else {
board += “#”;
}
}
board += “\n”;
}
console.log(board);
I don’t really understand how a loop within a loop works.
For the code above, when y = 0, the loop below will be executed until x = 7 right?
then the board += “\n” takes place to start a new line.
Then now y = 1 and we loop it again right?
But does x now still start at = 7?
Not too sure how it works.
