- Matches by Object property
```js
const { matches } = require('z')
const person = { name: 'Maria' }
matches(person)(
(x = { name: 'John' }) => console.log('John you are not welcome!'),
(x) => console.log(Hey ${x.name}, you are welcome!)
)
- Matches by type or instancesjs
const { matches } = require('z')
const result = matches(1)(
(x = 2) => 'number 2 is the best!!!',
(x = Number) => number ${x} is not that good,
(x = Date) => 'blaa.. dates are awful!'
)
console.log(result) // output: number 1 is not that good
- Matches Array contentjs
const { matches } = require('z')
matches([1, 2, 3, 4, 5])(
(a, b, c, tail) => 'a = 1, b = 2, c = 3, tail = [4, 5]'<br />
)
matches([1, 2])(
(a, tail) => 'a = 1, tail = [2]'<br />
)
matches([1])(
(a, b, tail) => 'Will not match here',
(a = 2, tail = []) => 'Will not match here',
(a = 1, tail) => 'Will match here, tail = []'
)
```
- Powerful recursive code which will remove sequential repeated items from Array
```js
const { matches } = require('z')
const compress = (numbers) => {
return matches(numbers)(
(x, y, xs) => x === y
? compress([x].concat(xs))
: [x].concat(compress([y].concat(xs))),
(x, xs) => x // stopping condition
)
}
compress([1, 1, 2, 3, 4, 4, 4]) //output: [1, 2, 3, 4]
```
