How to change the name of a variable, simultaneously throughout the code, but within the scope of this variable?

Question

JavaScript

So we declared a variable and we carry out some manipulations with it in the code. And we suddenly changed our minds and decided to name the variable differently. This could be done by autocorrect throughout the code. But I want to do it within the scope (accessibility) of the variable. It's about js and webstorm. You can give examples from other languages ​​and IDEs.
