```bash

npm i rxmetics

```

This is a minimal RxJS library for lazy people. Instead of this:

```ts

import { combineLatest, ... } from 'rxjs';

import { map, ... } from 'rxjs/operators';

// ...

combineLatest(a, b).pipe(map(([a, b]) => a + b))...

```

You can do this:

```ts

import { add } from 'rxmetics';

// ...

add(a, b)...

```

Or this:

```ts

import { add } from 'rxmetics/pipes';

// ...

a.pipe(add(b))...

```

But its not just for numbers (its RxJS arithmetic**s**):

```ts

import { and, eq } from 'rxmetics';

// ...

and(a.pipe(eq(32)), b.pipe(eq('halo')))...

```

```ts

import { rxl } from 'rxmetics';

import { interval } from 'rxjs';

// ...

rxl`hellow ${interval(1000)}`.subscribe(console.log);

// RESULT:

// > hellow

// > hellow 1

// > hellow 2

// > hellow 3

// ...

```
