JavaScript functions can be written as a declarations (function foo() { ... }) or as a expressions (const foo = function() { ... };). While a JavaScript interpreter might tolerate it, overwriting/reassigning a function written as a declaration is often indicative of a mistake.

Bad Practice

function foo() {}
foo = bar;

function foo() {
    foo = bar;
}

Recommended

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

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

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