cnc-tskit

A bunch of TypeScript functions and constants as used by miscellaneous web applications developed and maintained by the Czech National Corpus.

The library does not use any external dependencies.

How to use in a project

1. Install:

npm install cnc-tskit --save

2. Use in your code:

import { pipe, tuple, Dict, List } from 'cnc-tskit';

function uniqItems(...d:Array<string|Array<string>>):Array<string> {
    return pipe(
        d,
        List.filter(v => !!v),
        List.flatMap(v => typeof v === 'string' ? [v] : v),
        List.map(v => tuple(v, true)),
        Dict.fromEntries(),
        Dict.keys()
    );
}
