# {%= name %} {%= badge("fury") %} > {%= description %} ## Benchmarks ```bash node benchmark ``` ## Example usage ```js var expand = require('{%= name %}'); expand('1..3') //=> ['1', '2', '3'] expand('5..8') //=> ['5', '6', '7', '8'] expand('00..05') //=> ['00', '01', '02', '03', '04', '05'] expand('01..03') //=> ['01', '02', '03'] expand('000..005') //=> ['000', '001', '002', '003', '004', '005'] expand('a..e') //=> ['a', 'b', 'c', 'd', 'e'] expand('A..E') //=> ['A', 'B', 'C', 'D', 'E'] ``` ### Custom function Pass a function as the last argument to customize the expansions: **Params:** - `str` the expanded string - `ch` the [unicode value][unicode] for the string - `i` the current index **Example using the `str` value:** ```js var range = expand('a..e', function (str, ch, i) { return str + i; }); console.log(range); //=> ['a0', 'b1', 'c2', 'd3', 'e4'] ``` **Example using the unicode value:** ```js var range = expand('a..e', function (str, ch, i) { return String.fromCharCode(ch) + i; }); console.log(range); //=> ['a0', 'b1', 'c2', 'd3', 'e4'] ``` ## Install {%= include("install") %} ## Run tests ```bash npm test ``` ## Contributing Pull requests and stars are always welcome.
