# --description--
|
|
|
|
Given a string, return its camel case version using the following rules:
|
|
|
|
- Words in the string argument are separated by one or more characters from the following set: space (` `), dash (`-`), or underscore (`_`). Treat any sequence of these as a word break.
|
|
- The first word should be all lowercase.
|
|
- Each subsequent word should start with an uppercase letter, with the rest of it lowercase.
|
|
- All spaces and separators should be removed.
|
|
|
|
# --hints--
|
|
|
|
`to_camel_case("hello world")` should return `"helloWorld"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(to_camel_case("hello world"), "helloWorld")`)
|
|
}})
|
|
```
|
|
|
|
`to_camel_case("HELLO WORLD")` should return `"helloWorld"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(to_camel_case("HELLO WORLD"), "helloWorld")`)
|
|
}})
|
|
```
|
|
|
|
`to_camel_case("secret agent-X")` should return `"secretAgentX"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(to_camel_case("secret agent-X"), "secretAgentX")`)
|
|
}})
|
|
```
|
|
|
|
`to_camel_case("FREE cODE cAMP")` should return `"freeCodeCamp"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(to_camel_case("FREE cODE cAMP"), "freeCodeCamp")`)
|
|
}})
|
|
```
|
|
|
|
`to_camel_case("ye old-_-sea faring_buccaneer_-_with a - peg__leg----and a_parrot_ _named- _squawk")` should return `"yeOldSeaFaringBuccaneerWithAPegLegAndAParrotNamedSquawk"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(to_camel_case("ye old-_-sea faring_buccaneer_-_with a - peg__leg----and a_parrot_ _named- _squawk"), "yeOldSeaFaringBuccaneerWithAPegLegAndAParrotNamedSquawk")`)
