如何将数组中的所有值与单个字符串分开

Question

我有数组，

let array = ["a,b,c"]

我想像这样转换它

let array = ["a","b","c"]

Answer 1

let array = ["a,b,c"]
console.log(array.join().split(","))

Answer 2

您可以使用 Array.prototype。平面地图。它允许您返回填充被展平的数组。

let array = ["a,b,c"];
console.log(array.flatMap(item => item.split(",")));

Answer 3

使用分割

const array = ["a,b,c"];

const output = array[0].split(",");

console.log(output);
