Is it possible to bine these two lines of code into one?

Meaning, can we do a ToString() and .replace() in one line?

var mySecondVar = myFirstVar.ToString()
mySecondVar = mySecondVar.replace("a","u");

Yes, you can chain the methods.

myFirstVar.toString().replace('a', 'u')

Note:

1. ToString should be toString
2. String#replace will only replace the first occurrence of the string. To replace all occurrences use replace with RegEx

You can use:

 var mySecondVar = myFirstVar.toString().replace("a","u");
