Language: JavaScript

Severity: Error

Category: Best Practices

Description

JavaScript interpreters might allow assigning to a function, but it is often a mistake and should not be allowed.

Non-Compliant Code Examples

function foo() {}
foo = bar;

function baz() {
    baz = bar;
}

var a = function hello() {
  hello = 123;
};

Compliant Code Examples

var foo = function () {}
foo = bar;

function baz(baz) { // `baz` is shadowed.
    baz = bar;
}

function qux() {
    var qux = bar;  // `qux` is shadowed.
}
