# --description--

|
|
Given a string of words, return a new string where each word is replaced by its length.
|
|
|
|
- Words in the given string will be separated by a single space
|
|
- Keep the spaces in the returned string.
|
|
|
|
For example, given `"hello world"`, return `"5 5"`.
|
|
|
|
# --hints--
|
|
|
|
`convertWords("hello world")` should return `"5 5"`.
|
|
|
|
```js
|
|
assert.equal(convertWords("hello world"), "5 5");
|
|
```
|
|
|
|
`convertWords("Thanks and happy coding")` should return `"6 3 5 6"`.
|
|
|
|
```js
|
|
assert.equal(convertWords("Thanks and happy coding"), "6 3 5 6");
|
|
```
|
|
|
|
`convertWords("The quick brown fox jumps over the lazy dog")` should return `"3 5 5 3 5 4 3 4 3"`.
|
|
|
|
```js
|
|
assert.equal(convertWords("The quick brown fox jumps over the lazy dog"), "3 5 5 3 5 4 3 4 3");
|
|
```
|
|
|
|
`convertWords("Lorem ipsum dolor sit amet consectetur adipiscing elit donec ut ligula vehicula iaculis orci vel semper nisl")` should return `"5 5 5 3 4 11 10 4 5 2 6 8 7 4 3 6 4"`.
|
|
|
|
```js
|
|
assert.equal(convertWords("Lorem ipsum dolor sit amet consectetur adipiscing elit donec ut ligula vehicula iaculis orci vel semper nisl"), "5 5 5 3 4 11 10 4 5 2 6 8 7 4 3 6 4");
