start
and end
are inclusive with their common difference step
.Array.from()
to create an array of the desired length.(end - start + 1)/step
and a map function to fill the array with the desired values in the given range.start
, to use a default value of 0
.step
, to use a default value of 1
.const initializeArrayWithRange = (end, start = 0, step = 1) =>
Array.from(
{ length: Math.ceil((end - start + 1) / step) },
(_, 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]
