Chrome developer tools javascript version

Question

When I open the Chrome Developer Tools JavaScript console to get a REPL, the version of JavaScript it uses seems lower than 1.8. let statements, new style functions, etc. give me syntax errors. Is there any way to change the JavaScript version used?

Thanks in advance.

The MDN page for each feature you're looking for will tell you whether you can expect them in another engine -- e.g., let is "Non-Standard." But, many of these features have been and are being discussed for ECMAScript 6 and later under the Harmony and Strawman namespaces. — Jonathan Lonowski

Chrome's JS engine conforms most closely to ECMAScript 5. The JavaScript version numbering scheme comes from Mozilla, and features such as let statements, yield, and others are Mozilla-only extensions to JavaScript.

I see. I didn't know that. Looks like destructuring assignment isn't available either. :(
