Updating vs Setting variables


Updating vs Setting variables

When changing a variable value, you could either set it to a new value all together, or update it based on its previous value.

For example, if we have a variable called time and we want to add 5 to it, we write:

time = time + 5;

This will Add 5 to whatever value time already had!

But if we want to set time to 5 without caring about what the current value was, we write:

time = 5;
