 <p>In ECMAScript 2015, <strong><code>let</code></strong> bindings are not subject to <strong>Variable Hoisting</strong>, which means that <strong><code>let</code></strong> declarations do not move to the top of the current execution context. Referencing the variable in the block before the initialization results in a <code><a href="/en-US/docs/JavaScript/Reference/Global_Objects/ReferenceError">ReferenceError</a></code> (contrary to a variable declared with <a href="/en-US/docs/Web/JavaScript/Reference/Statements/var#var_hoisting">var</a>, which will just have the undefined value). The variable is in a "temporal dead zone" from the start of the block until the initialization is processed.</p>
