I'm new here, I'm learning the programming language Go. I previously departed from an object-oriented programming language, so I'm a bit confused when it comes to pass-by-value and pass-by-reference topics

Please help to explain the difference between the two and examples of each programming language that uses the method. Thank You

If you pass something by value, you're passing the value the object represents. In contrast, if you pass something by reference, you're passing a reference to the object itself.

For example, take this sample variable a:

var a = "test"

Passing a by value means passing "test". If you modify what you passed, it will not affect a.
However, if you pass a by reference, you're passing a. This means that what you passed is a reference to the original variable a directly, and modifying it modifies a as well.
