Disallows the overwriting/reassignment of an existing function
Disallows the overwriting/reassignment of an existing function
Javascript allows for the reassignment of a function definition. This is generally a mistake on the developers part, or poor coding practice as code readability and maintainability will suffer.
Invalid:
function foo() {}
foo = bar;
const a = function baz() {
baz = "now I'm a string";
};
myFunc = existingFunc;
function myFunc() {}
Valid:
function foo() {}
const someVar = foo;
const a = function baz() {
const someStr = "now I'm a string";
};
const anotherFuncRef = existingFunc;
let myFuncVar = function () {};
myFuncVar = bar; // variable reassignment, not function re-declaration
