The ``++delete++`` operator can be used to remove a property from any object. Arrays are objects, so the ``++delete++`` operator can be used here too, but if it is, a hole will be left in the array because the indexes/keys won't be shifted to reflect the deletion. The proper method for removing an element at a certain index would be: * ``++Array.prototype.splice++`` - add/remove elements from the array * ``++Array.prototype.pop++`` - add/remove elements from the end of the array * ``++Array.prototype.shift++`` - add/remove elements from the beginning of the array == Noncompliant Code Example [source,javascript] ---- var myArray = ['a', 'b', 'c', 'd']; delete myArray[2]; // Noncompliant. myArray => ['a', 'b', undefined, 'd'] console.log(myArray[2]); // expected value was 'd' but output is undefined ---- == Compliant Solution [source,javascript] ---- var myArray = ['a', 'b', 'c', 'd']; // removes 1 element from index 2 removed = myArray.splice(2, 1); // myArray => ['a', 'b', 'd'] console.log(myArray[2]); // outputs 'd' ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::message.adoc[] ''' == Comments And Links (visible only on this page) include::comments-and-links.adoc[] endif::env-github,rspecator-view[]
