Description
In JavaScript, variables can be assigned during declaration, or at any point afterwards using an assignment statement. For example, in the following code, foo is initialized during declaration, while bar is initialized later.
var foo = 1;
var bar;
if (foo) {
bar = 1;
} else {
bar = 2;
}
Bad Practice
function foo() {
var bar;
let baz;
}
Recommended
function foo() {
var bar = 1;
let baz = 2;
const qux = 3;
}
