Automatically updating the actual parameters in javascript
javascript
Solution
Primitive types, that is strings/numbers/booleans are passed by value. Objects such as functions, objects, arrays are "passed" by reference.
So, what you want won't be possible, but the following will work:
var myObj = {};
myObj.str = "this is a string";
function myFunction(obj){
// automatically have to reflect the change in str when i change the arg value
obj.str = "This is new string";
// Expected value of str is "This is new string"
}
myFunction(myObj);
console.log(myObj.str);
Problem
How to pass a primitive variable (like a string) by reference when calling a java script method? Which is equivalent of out or ref keyword in C#. I have a variable like `var str = "this is a string";` and passing the str into my function and automatically have to reflect the change in str when i change the argument value ``` function myFunction(arg){ // automatically have to reflect the change in str when i change the arg value arg = "This is new string"; // Expected value of str is "This is new string" } ```
