Your function should take in a string as a parameter.
|
|
|
|
```js
|
|
assert.match(capitalize.toString(), /\s*capitalize\(\s*\w+\s*\)/);
|
|
```
|
|
|
|
Your function should return a new string with the first letter capitalized.
|
|
|
|
```js
|
|
assert.strictEqual(capitalize('sem'), 'Sem');
|
|
```
