Disallow Use of caller/callee (no-caller)

The use of arguments.caller and arguments.callee make several code optimizations impossible. They have been deprecated in future versions of JavaScript and their use is forbidden in ECMAScript 5 while in strict mode.

function foo() {
    var callee = arguments.callee;
}

Rule Details

This rule is aimed at discouraging the use of deprecated and sub-optimal code by disallowing the use of arguments.caller and arguments.callee. As such, it will warn when arguments.caller and arguments.callee are used.

Examples of incorrect code for this rule:

/*eslint no-caller: "error"*/

function foo(n) {
    if (n <= 0) {
        return;
    }

    arguments.callee(n - 1);
}

[1,2,3,4,5].map(function(n) {
    return !(n > 1) ? 1 : arguments.callee(n - 1) * n;
});

Examples of correct code for this rule:

/*eslint no-caller: "error"*/

function foo(n) {
    if (n <= 0) {
        return;
    }

    foo(n - 1);
}

[1,2,3,4,5].map(function factorial(n) {
    return !(n > 1) ? 1 : factorial(n - 1) * n;
});
