将一个数组中的每个值与另一个数组中的每个值合并

Question

有没有可以采用两个数组并将其各自值组合在一起的东西？而且数组的长度不一样。像这样：

array1 = ["one", "two", "three"];
array2 = ["twenty", "thirty", "forty", "fifty"]

arrayWant= ["twentyone", "twentytwo", "twentythree", "thirtyone", "thirtytwo", "thirtythree", "fortyone", "fortytwo", "fortythree"...]

Answer 1

javascript中没有等效项。但是你可以写自己。

let array1 = ["one", "two", "three"];
let array2 = ["twenty", "thirty", "forty", "fifty"]

let arrayWant= array2.map(x=>array1.map(y=>x+y)).flat()

console.log(arrayWant)

此外，Array.forEach将返回undefined，因此您应使用map。
