Initializes and fills an array with the specified values.

• Use the Array() constructor to create an array of the desired length.
• Use Array.prototype.fill() to fill it with the desired values.
• Omit the last argument, 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]
