Sometimes, we want to create an array of all integers between two numbers, inclusive, in JavaScript.
In this article, we’ll look at how to create an array of all integers between two numbers, inclusive, in JavaScript.
Create an Array of All Integers Between Two Numbers, Inclusive, in JavaScript
To create an array of all integers between two numbers, inclusive, in JavaScript, we can use the Array.from method to create an array with a given length and includes integers between 2 numbers.
For instance, we can write:
const arr = Array.from({
length: 5
}, (v, k) => k + 1)
console.log(arr)
to call Array.from with an object with the length property to specify the length of the array.
The callback passed in as the 2nd argument returns a number that we want to include.
Therefore, arr is [1, 2, 3, 4, 5] .
Conclusion
To create an array of all integers between two numbers, inclusive, in JavaScript, we can use the Array.from method to create an array with a given length and includes integers between 2 numbers.
