The characteristics of a const anonymous function in JavaScript

I keep encountering an issue when attempting to determine the length of an anonymous array. I am uncertain if this operation is permitted or not.

const gamearena = function ()
{
    var matrix = [];
    var height = 20;
    var width = 10;

    while(height--)
        matrix.push(new Array(width).fill(0));

    return matrix;
};

Whenever I attempt to retrieve the array length, I am confronted with the error message "Cannot read property 'length' of undefined".

I am utilizing NetBeans and although the browser recognizes the constant as an array, it appears that there may be an issue where an anonymous function is concerned. Should I refrain from using an anonymous function in this scenario?

Answer №1

Your ongoing gameplay experience is not an array but a function. To retrieve the length of the array, you can use the following code:

console.log(gameplayExperience().length);

To log individual elements, you can iterate through the array using the following code:

for (var i = 0; i < gameplayExperience().length; i++) {
    console.log(gameplayExperience()[i]);
}
