Creates an array of numbers in the arithmetic progression, starting with the given positive integer and up to the specified limit.
|
|
|
|
- Use `Array.from()` to create an array of the desired length, `lim / n`. Use a map function to fill it with the desired values in the given range.
|
|
|
|
```js
|
|
const arithmeticProgression = (n, lim) =>
|
|
Array.from({ length: Math.ceil(lim / n) }, (_, i) => (i + 1) * n );
|
|
```
|
|
|
|
```js
|
|
arithmeticProgression(5, 25); // [5, 10, 15, 20, 25]
|
|
```
