In this article, we’ll look at how to get a range of items from a JavaScript array.
How to get a range of items from a JavaScript array?
To get a range of items from a JavaScript array, we can use the array slice method.
For instance, we write
const fruits = ["apple", "banana", "peach", "plum", "pear"];
const slice1 = fruits.slice(1, 3);
const slice2 = fruits.slice(3);
to call fruits.slice with 1 and 3 to return an array from fruits at index 1 and 2.
Next, we call slice with 3 to return an array from fruits at index 3 to the end of the array.
Therefore, slice1 is ['banana', 'peach'].
And slice2 is ['plum', 'pear'].
Conclusion
To get a range of items from a JavaScript array, we can use the array slice method.
