在下面的示例中，未映射的數(shù)組項(xiàng)必須映射到左側(cè)的 rest 參數(shù)，但由于某種原因輸出不同，var planets = ["Mercury", "Earth", "Venus", "Mars", "Pluto", "Saturn"];var [first, second, ...rest] = ["Mercury", "Earth", ...planets, "Saturn"];console.log(first); //Output: Mercuryconsole.log(second); //Output: Earth現(xiàn)在對(duì)于下面，預(yù)期的輸出是，console.log(rest); //Output: ["Venus", "Mars", "Pluto", "Saturn"]但實(shí)際輸出是，console.log(rest); //Output: "Mercury", "Earth", "Venus", "Mars", "Pluto", "Saturn", "Saturn"來(lái)源：https ://www.freecodecamp.org/news/array-destructuring-in-es6-30e398f21d10/這里發(fā)生了什么事？
