You can use String.prototype.replace()
by providing a regex to find BTC/USDC
and then return the string with the updated data using callback pattern您可以通过提供正则表达式来使用
String.prototype.replace()
来查找BTC/USDC
,然后使用回调模式返回带有更新数据的字符串
var str= "This post contains forecast for BTC/USDC This message was written by guest user, and is available at site.com" const newStr= str.replace(/BTC\/USDC/, (match) => { return `${match}.`; }) console.log(newStr);
