タプルを受け取り、その各値のkey/valueを持つオブジェクトの型に変換する型を実装します。
例えば：
const tuple = ['tesla', 'model 3', 'model X', 'model Y'] as const
type result = TupleToObject<typeof tuple> // expected { 'tesla': 'tesla', 'model 3': 'model 3', 'model X': 'model X', 'model Y': 'model Y'}
import type { Equal, Expect } from '@type-challenges/utils'
const tuple = ['tesla', 'model 3', 'model X', 'model Y'] as const
const tupleNumber = [1, 2, 3, 4] as const
const sym1 = Symbol(1)
const sym2 = Symbol(2)
const tupleSymbol = [sym1, sym2] as const
const tupleMix = [1, '2', 3, '4', sym1] as const
type cases = [
Expect<Equal<TupleToObject<typeof tuple>, { 'tesla': 'tesla', 'model 3': 'model 3', 'model X': 'model X', 'model Y': 'model Y' }>>,
Expect<Equal<TupleToObject<typeof tupleNumber>, { 1: 1, 2: 2, 3: 3, 4: 4 }>>,
Expect<Equal<TupleToObject<typeof tupleSymbol>, { [sym1]: typeof sym1, [sym2]: typeof sym2 }>>,
Expect<Equal<TupleToObject<typeof tupleMix>, { 1: 1, '2': '2', 3: 3, '4': '4', [sym1]: typeof sym1 }>>,
]
// @ts-expect-error
type error = TupleToObject<[[1, 2], {}]>
