### 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`.
|
|
|
|
```js
|
|
const initializeArrayWithRange = (end, start = 0, step = 1) =>
|
|
Array.from({ length: Math.ceil((end + 1 - start) / step) }).map((v, i) => i * step + start);
|
|
```
|
|
|
|
```js
|
|
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]
|
|
```
