如何在JavaScript中替换一部分字符串并等待任务完成，然后继续使用其余代码

let searchKeyword = 'hi'
Array[lastIndex]= await Array[lastIndex].replace(searchKeyword,'user_id:12345,"email":mail') /*wait for this line of code to finish executing, before continuing on with rest of code */
logger.info('hi')

我是否必须使用诺言，我尝试使用等待，但它说等待对这种表达没有影响。我有更多的代码，但这只是我要实现的基本思想，我仍然有异步编程并了解等待和承诺是新的。

原文

let searchKeyword = 'hi'
Array[lastIndex]= await Array[lastIndex].replace(searchKeyword,'user_id:12345,"email":mail') /*wait for this line of code to finish executing, before continuing on with rest of code */
logger.info('hi')

do i have to use promises, I tried using await but it says await has no affect on this type of expression. i have more code but this is just the basic idea I am trying to accomplish, I am still new with asynchronous programming and learn about await and promises
