    The purpose of the delete operator is to remove a property from an object. Using the delete operator on a variable might lead to unexpected behavior.

    Examples of incorrect code for this rule:

    var x;
delete x;

    Examples of correct code for this rule:

    var obj = { x: 1 };
delete obj.x;
