+
+> 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`
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save fill-range
+```
+
+## Usage
+
+Expands numbers and letters, optionally using a `step` as the last argument. _(Numbers may be defined as JavaScript numbers or strings)_.
+
+```js
+const fill = require('fill-range');
+// fill(from, to[, step, options]);
+
+console.log(fill('1', '10')); //=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
+console.log(fill('1', '10', { toRegex: true })); //=> [1-9]|10
+```
+
+**Params**
+
+* `from`: **{String|Number}** the number or letter to start with
+* `to`: **{String|Number}** the number or letter to end with
+* `step`: **{String|Number|Object|Function}** Optionally pass a [step](#optionsstep) to use.
+* `options`: **{Object|Function}**: See all available [options](#options)
+
+## Examples
+
+By default, an array of values is returned.
+
+**Alphabetical ranges**
+
+```js
+console.log(fill('a', 'e')); //=> ['a', 'b', 'c', 'd', 'e']
+console.log(fill('A', 'E')); //=> [ 'A', 'B', 'C', 'D', 'E' ]
+```
+
+**Numerical ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill(1, 5)); //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill('1', '5')); //=> [ 1, 2, 3, 4, 5 ]
+```
+
+**Negative ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill('-5', '-1')); //=> [ '-5', '-4', '-3', '-2', '-1' ]
+console.log(fill('-5', '5')); //=> [ '-5', '-4', '-3', '-2', '-1', '0', '1', '2', '3', '4', '5' ]
+```
+
+**Steps (increments)**
+
+```js
+// numerical ranges with increments
+console.log(fill('0', '25', 4)); //=> [ '0', '4', '8', '12', '16', '20', '24' ]
+console.log(fill('0', '25', 5)); //=> [ '0', '5', '10', '15', '20', '25' ]
+console.log(fill('0', '25', 6)); //=> [ '0', '6', '12', '18', '24' ]
+
+// alphabetical ranges with increments
+console.log(fill('a', 'z', 4)); //=> [ 'a', 'e', 'i', 'm', 'q', 'u', 'y' ]
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 6)); //=> [ 'a', 'g', 'm', 's', 'y' ]
+```
+
+## Options
+
+### options.step
+
+**Type**: `number` (formatted as a string or number)
+
+**Default**: `undefined`
+
+**Description**: The increment to use for the range. Can be used with letters or numbers.
+
+**Example(s)**
+
+```js
+// numbers
+console.log(fill('1', '10', 2)); //=> [ '1', '3', '5', '7', '9' ]
+console.log(fill('1', '10', 3)); //=> [ '1', '4', '7', '10' ]
+console.log(fill('1', '10', 4)); //=> [ '1', '5', '9' ]
+
+// letters
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 7)); //=> [ 'a', 'h', 'o', 'v' ]
+console.log(fill('a', 'z', 9)); //=> [ 'a', 'j', 's' ]
+```
+
+### options.strictRanges
+
+**Type**: `boolean`
+
+**Default**: `false`
+
+**Description**: By default, `null` is returned when an invalid range is passed. Enable this option to throw a `RangeError` on invalid ranges.
+
+**Example(s)**
+
+The following are all invalid:
+
+```js
+fill('1.1', '2'); // decimals not supported in ranges
+fill('a', '2'); // incompatible range values
+fill(1, 10, 'foo'); // invalid "step" argument
+```
+
+### options.stringify
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Cast all returned values to strings. By default, integers are returned as numbers.
+
+**Example(s)**
+
+```js
+console.log(fill(1, 5)); //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill(1, 5, { stringify: true })); //=> [ '1', '2', '3', '4', '5' ]
+```
+
+### options.toRegex
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Create a regex-compatible source string, instead of expanding values to an array.
+
+**Example(s)**
+
+```js
+// alphabetical range
+console.log(fill('a', 'e', { toRegex: true })); //=> '[a-e]'
+// alphabetical with step
+console.log(fill('a', 'z', 3, { toRegex: true })); //=> 'a|d|g|j|m|p|s|v|y'
+// numerical range
+console.log(fill('1', '100', { toRegex: true })); //=> '[1-9]|[1-9][0-9]|100'
+// numerical range with zero padding
+console.log(fill('000001', '100000', { toRegex: true }));
+//=> '0{5}[1-9]|0{4}[1-9][0-9]|0{3}[1-9][0-9]{2}|0{2}[1-9][0-9]{3}|0[1-9][0-9]{4}|100000'
+```
+
+### options.transform
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+**Description**: Customize each value in the returned array (or [string](#optionstoRegex)). _(you can also pass this function as the last argument to `fill()`)_.
+
+**Example(s)**
+
+```js
+// add zero padding
+console.log(fill(1, 5, value => String(value).padStart(4, '0')));
+//=> ['0001', '0002', '0003', '0004', '0005']
+```
