There was typo mistake in which Array.from was missing from Array(Math.ceil((end+1-start)/step) in description of snippet

initializeArrayWithRange
Initializes an array containing the numbers in the specified range where start and end are inclusive with there common difference step.
Use Array.from(Math.ceil((end+1-start)/step)) to create an array of the desired length(the amounts of elements is equal to (end-start)/step or (end+1-start)/step for inclusive end), Array.map() to fill with the desired values in a range.
You can omit start to use a default value of 0.
You can omit step to use a default value of 1.
const initializeArrayWithRange = (end, start = 0, step = 1) =>
Array.from({ length: Math.ceil((end + 1 - start) / step) }).map((v, i) => i * step + start);
initializeArrayWithRange(5); // [0,1,2,3,4,5]
initializeArrayWithRange(7, 3); // [3,4,5,6,7]
initializeArrayWithRange(9, 0, 2); // [0,2,4,6,8]
