Implement TrimLeft<T> which takes an exact string type and returns a new string with the whitespace beginning removed.
For example
type trimed = TrimLeft<' Hello World '> // expected to be 'Hello World '
/* _____________ Your Code Here _____________ */
type SpaceType = ' ' | '\n' | '\t'
type TrimLeft<S extends string> = S extends `${infer Space}${infer REST}` ? Space extends SpaceType ? TrimLeft<REST> : S: ''
/* _____________ Test Cases _____________ */
import type { Equal, Expect } from '@type-challenges/utils'
type cases = [
Expect<Equal<TrimLeft<'str'>, 'str'>>,
Expect<Equal<TrimLeft<' str'>, 'str'>>,
Expect<Equal<TrimLeft<' str'>, 'str'>>,
Expect<Equal<TrimLeft<' str '>, 'str '>>,
Expect<Equal<TrimLeft<' \n\t foo bar '>, 'foo bar '>>,
Expect<Equal<TrimLeft<''>, ''>>,
Expect<Equal<TrimLeft<' \n\t'>, ''>>,
]
