1. split()方法
- 通过空字符串作为分隔符
const info = "字符串abc123";const arr = info.split('');console.log(arr);// ["字", "符", "串", "a", "b", "c", "1", "2", "3"]- 通过符号作为分隔符
const info = "字,符串,ab,c12,3";const arr = info.split(',');console.log(arr);// ["字", "符串", "ab", "c12", "3"]2. Array.from
- 将一个类数组对象（有length属性的对象）或者可遍历对象转换成一个真正的数组
const info = "字符串abc456";const arr = Array.from(info)console.log(arr);// ["字", "符", "串", "a", "b", "c", "4", "5", "6"]3. 展开运算符
- 展开运算符（...） 允许在需要多个元素（如数组文字）的地方扩展诸如字符串之类的可迭代对象。
const info = "字符串abc789";const arr = [ ...info ]console.log(arr);// ["字", "符", "串", "a", "b", "c", "7", "8", "9"]
