Update the string value in the object based on the parameter - Typescript

Question

I have exported an object in a separate ts file and I would like that to be parameterized

export const customer = {
  comment: 'Wow, this is great because {{username}} is doing what we needed' 
};

Then in another ts file, I get this constant but I want to pass the value of username

import * as customerConstants from 'constants';
export class CustomerComponent implements OnInit{
 username ='learn' 
 customerData = customerConstants.customer ;

  ngOnInit(): void {
    this.customerData.comment = customerData + username;
  }

I want to put learn in place of username in the customer const. Is it possible?

由于customer.comment是字符串，您可以使用replace()将'{{username}}'替换为username变量值。
