Question about using a variable in selectors

Hi everyone~
I found two ways to use variables in selectors.

  1. {{variable}}
  2. ‘""+variable+’" (single & double quot combinations)

It looks the first method is more simple and easy to use.
Whats the difference of the two methods above?

Both are same way of creating or inserting a variable of type STRING inside a string with double quotes

Initially we had the second option of creating a variable in a selector

But later we got an enhancement of creating a variable inside the selector editor itself by right clicking and creating a variable like this
