我想做这样的事情:
[1,[2],[3,4]] + " is a Nested Array."
=> "[1,[2],[3,4]] is a Nested Array."
但是,
console.log([1,[2],[3,4]] + " is a Nested Array.");
给出1,2,3,4 is a Nested Array.
我可以通过在字符串中添加方括号并使数组变平来实现单维数组:
"["+ [1,2,3,4,5] + "] is a single dimensional array."
=> "[1,2,3,4,5] is a single dimensional array."
