Consider this scenario: I have an array and I need to remove a specific element from it. Take the following array for example:
arr = [1, 2 , 3, 4, 5]
if (value === 3){
arr.pop() // If the value is '3', I want to remove that record from the array regardless of its position within the list.
My question is, can this be achieved?
To achieve this, utilize the splice function.
let index = array.indexOf(5);
if(index !== -1) {
array.splice(index, 1);
}
To exclude specific item(s) from an array, you can utilize the filter function:
arr = arr.filter(function(item){ return item !== 3; });
This method will eliminate the specified value from the array, even if it appears multiple times.
(It is important to consider browser compatibility before using this approach. The filter function may not be supported in older browsers like IE 8.)
