Hi Friends, In this video, we are going to learn the difference between "call by Value" & "Call by reference" in javaScript.

When a variable’s reference(address) and not its value is passed to a function’s parameter, any changes made to the parameter will update the original variable reference. This is known as call by reference and this is true for all values having a non-primitive data type.

When a variable is passed as a parameter to a function, if any changes are made to the parameter, the original variable will remain unaffected. This is known as call by value and this is true for all values having a primitive data type.
