Learn JavaScript concepts with the Chrome DevTools

Authored by Peter Rybin , Chrome DevTools team

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.

Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:

TYPO3 Dynamic Return Type code completion

When using PhpStorm:

install DynamicReturnTypePlugin from http://plugins.jetbrains.com/plugin/7251?pr=phpStorm&showAllUpdates=true
add dynamicReturnTypeMeta.json to your TYPO3 CMS project root
live a better life

You're welcome, you owe me a beer.
