Deleting array elements in JavaScript - delete vs splice

Question

What is the difference between using the delete operator on the array element as opposed to using the Array.splice method?

For example:

myArray = [\         


        

Answer 1

Why not just filter? I think it is the most clear way to consider the arrays in js.

myArray = myArray.filter(function(item){
    return item.anProperty != whoShouldBeDeleted
});
