Numerical Packages

Bash-like brace expansion, implemented in JavaScript. Safer than other brace expansion libs, with complete support for the Bash 4.3 braces specification, without sacrificing speed.

Fill in a range of numbers or letters, optionally passing an increment or `step` to use, or create a regex-compatible range with `options.toRegex`

Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.

Check if a character is alphanumerical

Fast, bash-like range expansion. Expand a range of numbers or letters, uppercase or lowercase. Used by micromatch.

Wrapper for [braces] to enable brace expansion for arrays of patterns.
