# Fuse
**FunctionSelect**
`Fuse` selects a function that passes a condition.
## Usage
```JavaScript
const Fuse = require('@codefeathers/fuse');
const { FuseIterable } = require('@codefeathers/fuse');
const a = 100;
const result = new Fuse(a)
.on(x => x>10,
a => `${a} is greater than 10.`)
.on(x => x<10,
a => `${a} is lesser than 10.`)
.on(x => x===10,
a => `${a} is 10.`)
console.log(result.resolve());
const arr = [ 0, 20, 30 ];
const temperature = new FuseIterable(arr)
.on(temp => temp<10,
() => `Too cold!`)
.on(temp => temp>=10 && temp <25,
() => `Just right.`)
.on(temp => temp>=25,
() => `Too warm!`)
console.log(temperature.resolve()); // -> [ "Too cold!", "Just right.", "Too warm!" ]
```
## Docs
Docs exist in `/docs` directory. Will be served soon.
## Development
> If you find any mistakes in code/documentation, or if you feel something could be done better, do PR :) I appreciate it.
- Always write test spec for any code you add. Make sure they run as intended.
- Add/update JSDoc comments as needed.
- Use npm scripts for linting, tests, debugging, building docs.
Place your test file as `testscript.js` in root.
The following npm scripts are available: `npm run lint`, `npm test`, `npm run debug`, `npm run docs`.
