I was wondering how can I get the multidimensional array like [[A1, B1, C1....],[A2, B2, C2....]];
let grid = [
[]
];
let letters = "abcdefghij".toUpperCase();
// create the Grid
const createGrid = (size) => {
let row = 0;
let col = 0;
for (row = 0; row < size; row++) {
grid[row] = [];
for (col = 0; col < letters.length; col++) {
grid[row][col] = `${letters[row]}${col + 1}`;
}
}
};
createGrid(letters.length);
console.log(grid);If you don't mind converting your code to ES6+, this one should do the trick.
const letters = "abcdefghij".toUpperCase();
const createGrid = (letters) => Array.from(
{ length: letters.length },
(_, index) => [...letters].map((letter) => `${letter}${index + 1}`)
);
console.log(createGrid(letters));Just refer the col instead of the row and concat the row + 1 to it in the inner loop when you are doing the assignment.
let grid = [
[]
];
let letters = "abcdefghij".toUpperCase();
// create the Grid
const createGrid = (size) => {
let row = 0;
let col = 0;
for (row = 0; row < size; row++) {
grid[row] = [];
for (col = 0; col < letters.length; col++) {
// instead of grid[row][col] = `${letters[row]}${col + 1}`;
grid[row][col] = `${letters[col]}${row + 1}`;
}
}
};
createGrid(letters.length);
console.log(grid);
rowandcolin your cell assignment like${letters[col]}${row + 1}
