javascript是否有替换字符串的一部分而不创建新字符串的方法? [英] Does javascript have a method to replace part of a string without creating a new string?

问题描述

var str = "This is a string";
var thing = str.replace("string","thing");

console.log( str )
>> "This is a string" 

console.log( thing )
>> "This is a thing" 

除了replace之外，还有其他方法可以使用它来更改字符串而不给我新的字符串对象吗?

Is there another method I can use, besides replace, that will alter the string in place without giving me a new string object?

推荐答案

否，JavaScript中的字符串是不可变的.

No, strings in JavaScript are immutable.
