I have an array which looks like:-
[[0,1], [0,2], [0,3], [1,1], [1,2]...]
I am looking to remove one of the arrays from this array based on the indexOf()
but I keep getting a value of -1
, which removes the last item from the array when I try the following code:-
array = [[0,1], [0,2], [0,3], [1,1], [1,2]];
console.log('Removed value', array.splice(array.indexOf([0,3]), 1));
console.log('Result', array);
would somebody be able to point me in the right direction to help solve this issue I am having?
Thank you in advance.
You can't use indexOf
because when you declare [0,3]
in array.splice(array.indexOf([0,3]), 1))
you're creating a new array and this new object is not inside your array
(but rather another array that has the same values).
You can use findIndex
instead as follows (example):
array.findIndex(x => x[0] === 0 && x[1] === 3)
this will return 2
- now you can use it to delete:
array.splice(2, 1)
