Capitalizes the first letter of every word in a string.
|
|
|
|
- Use `String.prototype.replace()` to match the first character of each word and `String.prototype.toUpperCase()` to capitalize it.
|
|
|
|
```js
|
|
const capitalizeEveryWord = str =>
|
|
str.replace(/\b[a-z]/g, char => char.toUpperCase());
|
|
```
|
|
|
|
```js
|
|
capitalizeEveryWord('hello world!'); // 'Hello World!'
|
|
```
