This app will return word recommendations based on given clues and known letters to help you solve your next crossword puzzle.

It uses the Datamuse API to find words that have similar meaning to the phrase entered, as well as words that match the provided spelling pattern.

This app is using the Fetch API which is based on the Promise object and is supported by all modern browsers, except Internet Explorer and older mobile browsers. If you want to provide support for those browsers you can add polyfills for the Promise object and the Fetch API:

• Promise() Polyfill (Pushes support back to IE9)
• fetch() Polyfill (Pushes support back to IE10)

You can also use the Polyfill.io service in order to automate this process.

The ES6 template literals used in the app make it easier to add JSON data into a string, but are not supported in Internet Explorer and some mobile browsers.

To add support for ES6 syntax such as template literals, you must transpile the code to ES5 syntax using a compiler tool like Babel.
