### toTitleCase
|
|
|
|
Converts a string to title case.
|
|
|
|
Break the string into words, using a regexp, and combine them capitalizing the first letter of each word and adding a whitespace between them.
|
|
|
|
```js
|
|
const toTitleCase = 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.charAt(0).toUpperCase() + x.slice(1))
|
|
.join(' ');
|
|
```
|
|
|
|
```js
|
|
toTitleCase('some_database_field_name'); // 'Some Database Field Name'
|
|
toTitleCase('Some label that needs to be title-cased'); // 'Some Label That Needs To Be Title Cased'
|
|
toTitleCase('some-package-name'); // 'Some Package Name'
|
|
toTitleCase('some-mixed_string with spaces_underscores-and-hyphens'); // 'Some Mixed String With Spaces Underscores And Hyphens'
|
|
```
