I am looking to create a 3x3 grid using JavaScript for a web application. Each field should start with a value of false. However, my code doesn't seem to be functioning correctly and I'm having trouble locating the error. The objective is to ensure that every space sector is accessible.
This is what I have in mind:
// define size
var gridSize = generateGrid(3);
}
By assigning <code>false to space[i], you are only replacing the array with a single boolean value instead of populating all elements in the array you just initialized. You will need an additional loop to fill in all the values.
function generateSpace(x) {
var space = [];
for (var i = 0; i < x; i++) {
space[i] = [];
for (var j = 0; j < x; j++) {
space[i][j] = false;
}
}
return space;
}
Furthermore, the condition in your for() loop was incorrect because it was not initializing the last element of space. It should have been i < space.length.
Lastly, make sure to return the created array at the end of the function execution.
Feeling a bit restless, I decided to experiment with initializing datasets in a different way. Check out the code snippet below:
function createGrid(y) {
return Array.from({ length: y }, () => new Array(y).fill(false));
}
While all the other functions are effective, here is a straightforward implementation using ES6 that is suitable for any square grid:
function createGrid(x) {
return Array.from({ length: x }, () => Array.from({ length: x }).fill(false));
}
