Generate huffman encoded symbols from an alphabet and its frequencies

Build

npm install
npm run build

Test

npm test

Usage

Review test/huffman.spec.js for a complete test suite

let encoded;
let alphabet; // array of frequencies
let code = [0, 1, 2];

alphabet = [
		{s: 'A', f: 6},
		{s: 'B', f: 4},
		{s: 'C', f: 3},
		{s: 'D', f: 3},
		{s: 'E', f: 2},
		{s: 'F', f: 2}];

encoded = lib.encode(code, alphabet);

{ E: '20', F: '21', B: '00', C: '01', D: '02', A: '1' }
