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<'', '', ''>, ''>>,
