In Javascript, the locality of a variable is determined by the closest <code>var</code> statement for this variable. In the following example, <code>x</code> is local to <code>outer</code> as it contains a <code> var x</code> statement, while <code>inner</code> doesn't. Therefore, x is non-local to <code>inner</code>:

<source lang=javascript>

function outer() {

var x = 1;

function inner() {

x += 1;

console.log(x);
