Converts a string to kebab case.
|
|
|
|
- Use `String.prototype.match()` to break the string into words using an appropriate regexp.
|
|
- Use `Array.prototype.map()`, `Array.prototype.slice()`, `Array.prototype.join()` and `String.prototype.toLowerCase()` to combine them, adding `-` as a separator.
|
|
|
|
```js
|
|
const toKebabCase = str =>
|
|
str &&
|
|
str
|
|
.match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g)
|
|
.map(x => x.toLowerCase())
|
|
.join('-');
|
|
```
|
|
|
|
```js
|
|
toKebabCase('camelCase'); // 'camel-case'
|
|
toKebabCase('some text'); // 'some-text'
|
|
toKebabCase('some-mixed_string With spaces_underscores-and-hyphens');
|
|
// 'some-mixed-string-with-spaces-underscores-and-hyphens'
|
|
toKebabCase('AllThe-small Things'); // 'all-the-small-things'
|
|
toKebabCase('IAmEditingSomeXMLAndHTML');
|
|
// 'i-am-editing-some-xml-and-html'
|
|
```
