Initializes and fills an array with the specified values.

• Use Array(n) to create an array of the desired length, fill(v) to fill it with the desired values.
• You can omit val to use a default value of 0.

const initializeArrayWithValues = (n, val = 0) => Array(n).fill(val);

initializeArrayWithValues(5, 2); // [2, 2, 2, 2, 2]
