如何添加 append 并加入数组中的每个项目？

Question

myArr = [1,2,3,4,5]

I would like to join but also prepend and append to each item

Result: '$'1'^'|'$'2'^'|'$'3'^'|'$'4'^'|'$'5'^'|'$'6'^'

I have tried this:

console.log("$" + valArr.join("'|'") + "^");

which results in: '$'1'|'2'^'

I have tried: valArr.map(i => "'$'" + i).join("|"); but this only appends.

Answer 1

First map the array and then join it,

 const myArr = [1, 2, 3, 4, 5].map((i) => `'$'${i}'^'`).join("|"); console.log(myArr);
