To remove the first element of an array in JavaScript, use the shift() function.
For example, let’s return number 1 from this array of numbers:
var nums = [1, 2, 3] nums.shift() console.log(nums)
Result:
[2, 3]
Notice that shift() also returns the removed element. This is useful if you want to use it later.
For example:
var nums = [1, 2, 3]
const n = nums.shift()
console.log(`Removed ${n} from an array`)Output:
Removed 1 from an array
To remove the last item of an array, use the pop() function.
For example:
var nums = [1, 2, 3] nums.pop() console.log(nums)
Result:
[1, 2]
Conclusion
- To remove the first element of an array in JavaScript, use the shift() function.
- To remove the last element of an array, use the pop() function.
