A `var` declaration without an initializer does not overwrite the function's value.

```js
function foo() {
console.log(typeof a); // "function"
var a;
function a() {}
console.log(typeof a); // "function"
}

foo();
```

`var` declarations cannot be in the same scope as a {{jsxref("Statements/let", "let")}}, {{jsxref("Statements/const", "const")}}, {{jsxref("Statements/class", "class")}}, or {{jsxref("Statements/import", "import")}} declaration.
