### initializeArrayWithRange Initializes an array containing the numbers in the specified range. Use `Array(end-start)` to create an array of the desired length, `Array.map()` to fill with the desired values in a range. You can omit `start` to use a default value of `0`. ```js const initializeArrayWithRange = (end, start = 0) => Array.from({ length: end - start }).map((v, i) => i + start); // initializeArrayWithRange(5) -> [0,1,2,3,4] ```
