How to delete a specific item from an array in JS?


First way

Iterate through the array, and find the item you want to delete and then do delete list[index]

Initial list length - 5

list.forEach((index, item) ⇒ if( == 'No entry') delete list[item])

This will delete the item in the array but it leaves a void meaning - the array length will still remain the same → will be like final list length 5 - [1,2,3,4,empty]

Second way

list.forEach((index, item) ⇒ if( == 'No entry') list.splice(index, 1))

This will actually the remove the item and it's space from the array so the length of the array will be Initial(5) ⇒ Final(4)
