Generating a multi-dimensional array containing only the value 'false' in each sub-array

My goal is to create an array of arrays in JavaScript, with each inner array filled with the value false. However, I'm encountering an error message that says:

Uncaught TypeError: Cannot read property 'push' of undefined

The code I am currently using is as follows:

var fieldFilled = [];

for (var i = 0; i < 10; i++) {
    fieldFilled.push([]);
            
    for (var j = 0; j < 10; j++) {
        fieldFilled[j].push(false);
    }
}

I find it confusing because it appears that fieldFilled is defined. Any insights or assistance on this issue would be greatly appreciated.

Thank you for your guidance.

One possible solution is to utilize the functional programming technique:

const matrix = new Array(10).fill(0).map(row => new Array(10).fill(false));

console.log(matrix)
