Update to latest ECMAScript needed

I love using this app for quick references but the lack of current ES6 references is really damaging the usability. ES5 references are also missing.

Needs an update big time so we can see newer function usage like () => {}, new array functions, async functions, let and const variables, and much more.

Please update soon!

The information is accurate, well organized, and very nicely presented. It's also very comprehensive as "quick guide." Call me a geek, but it even makes a good "cover to cover" read. Well worth the current $0.99 price.

Simple app, could be better

The app is pretty straight forward. The layout is nice and clean, very easy to read. But the search function could use a lot of update to include searching the content instead of just the index.

For example, if you want to see how to write an if-else statement, you have to search "conditonals" because search "if" or "else" will give you "shift()", "unshift()", and "IFrame". So if you are not familiar with the coding already, this is very difficult to use.
