- 判断一个字符串是回文字符串，如 abcdcba是回文字符串, abcdcbb不是
var str = 'abcdcba';
function isreverse(str){
var newarry = str.split('');
var str2 = newarry.reverse().join('')
return (str === str2)
}
var result = isreverse(str);
console.log(result);
- 把my-short-string形式的字符串转化成myShortString形式的字符串
var str = 'my-short-string';
var str2 = str.split('-').join('');
console.log(str2);
