The best way to remove array element by value

Question

I have an array like this

arr = [\"orange\",\"red\",\"black\",\"white\"]

I want to augment the array object defining a deleteElem()<

Answer 1

Or simply check all items, create a new array with non equal and return it.

var arr = ['orange', 'red', 'black', 'white'];

console.info('before: ' + JSON.stringify(arr));

var deleteElem = function ( val ) {
    var new_arr = [];
    for ( var i = 0; i < this.length; i++ ) {
        if ( this[i] !== val ) {
            new_arr.push(this[i]);
        }
    }
    return new_arr;
};

arr = deleteElem('red');

console.info('after: ' + JSON.stringify(arr));
