题目

实现EndsWith<T, U>,接收两个string类型参数,然后判断T是否以U结尾,根据结果返回true或false

例如:

type a = EndsWith<'abc', 'bc'> // expected to be true
type b = EndsWith<'abc', 'abc'> // expected to be true
type c = EndsWith<'abc', 'd'> // expected to be false

解题思路

待补充

答案

type EndsWith<T extends string, U extends string> = any

验证

import type { Equal, Expect } from '@type-challenges/utils'

type cases = [
  Expect<Equal<EndsWith<'abc', 'bc'>, true>>,
  Expect<Equal<EndsWith<'abc', 'abc'>, true>>,
  Expect<Equal<EndsWith<'abc', 'd'>, false>>,
  Expect<Equal<EndsWith<'abc', 'ac'>, false>>,
  Expect<Equal<EndsWith<'abc', ''>, true>>,
  Expect<Equal<EndsWith<'abc', ' '>, false>>,
]
