Preserve final variable state - Angular

My function looks like this:

flag: boolean = false;

some_function(){
                var foo = some_num_value;
                var bar = foo;           // Storing value in a separate variable
                if(this.flag){
                               var total = bar + foo;
                             }
                   return total;
                   !this.flag;
               }

This particular function is executed 2 or 3 times within a single instance. The value of var foo changes with each iteration. I want to preserve the value of each var foo so that I can add it to the new value of var foo in the next iteration.

Any suggestions on how I can achieve this?

To optimize the code, consider moving "foo" outside of the method (function).

isFlagSet: boolean = false;
fooValue: number;

performCalculation(input){
                  
                
                if(this.isFlagSet){
                               var result = input + fooValue;
                             }
                   this.fooValue += input;
                   return result;
                   !this.isFlagSet;
               }
