let fn = (a, b, c) => {  console.log(a, b, c)}fn1(0, 0, 0) // output: 0 0 0想要 fn 每次調(diào)用的時(shí)候第二個(gè)參數(shù)總是加 2即fn(0, 0, 0) // output: 0 2 0fn(1, 1, 1) // output: 1 3 1目前只找到一種很丑的寫法去 hijack：fn = (_ => {  const innerFn = fn  const newFn = (a, b, c) => {    innerFn(a, b + 2, c)  }  Object.assign(newFn, innerFn)  return newFn})()有沒(méi)有更好一點(diǎn)的包裝方法？
