[Typescript] 90. Medium - Replace

Implement Replace<S, From, To> which replace the string From with To once in the given string S

For example

type replaced = Replace<'types are fun!', 'fun', 'awesome'> // expected to be 'types are awesome!'

 

/* _____________ Your Code Here _____________ */

type Replace<S extends string, From extends string, To extends string> = From extends '' 
  ? S
  : S extends `${infer A}${From}${infer B}`
    ? `${A}${To}${B}`
    : S;
  
/* _____________ Test Cases _____________ */
import type { Equal, Expect } from '@type-challenges/utils'

type cases = [
  Expect<Equal<Replace<'foobar', 'bar', 'foo'>, 'foofoo'>>,
  Expect<Equal<Replace<'foobarbar', 'bar', 'foo'>, 'foofoobar'>>,
  Expect<Equal<Replace<'foobarbar', '', 'foo'>, 'foobarbar'>>,
  Expect<Equal<Replace<'foobarbar', 'bar', ''>, 'foobar'>>,
  Expect<Equal<Replace<'foobarbar', 'bra', 'foo'>, 'foobarbar'>>,
  Expect<Equal<Replace<'', '', ''>, ''>>,
