Package Exports

expand-range

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (expand-range) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Expand a range of numbers or letters, uppercase or lowercase. Super fast, see the benchmarks.

Example usage

var expand = require('expand-range');

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']

Pass a function as the last argument to customize the expansions:

var range = expand('a..e', function (str, i) {
  return String.fromCharCode(str) + i;
});

console.log(range);
//=> ['a0', 'b1', 'c2', 'd3', 'e4']
