It takes two parameters: the starting index and the ending index, with both being inclusive or exclusive depending on how it’s used. The `slice` method in JavaScript is a useful tool for extracting sections of an array into a new array. Note that the `slice` method does not modify the original array, but returns a new array with the extracted elements.
In `slice3`, we extract the last two elements of the array. In `slice2`, we extract all the elements from index 2 (inclusive) to the end of the array. In `slice1`, we extract the elements between index 1 (inclusive) and index 3 (exclusive), which are `’banana’` and `’orange’`. We then use the `slice` method to extract a section of the array into a new array. In this example, we have an array called `fruits`. It takes two parameters: the starting index and the ending index.Ĭonst fruits = Ĭonst slice1 = fruits.slice(1, 3) // Ĭonst slice2 = fruits.slice(2) // Ĭonst slice3 = fruits.slice(-2) // You can use the `slice` method in JavaScript to extract a section of an array into a new array. We’ll look at examples and explain what parameters are needed, as well as how it works without modifying the original array.
