Value semantics
Imagine you have a toy car. It is red and has four wheels. This toy car is just like any other car, but it is your car. You love playing with it and take it everywhere with you.
Now let's say you have a friend who also has a toy car. His car is green and also has four wheels. You both love playing with your cars, but the cars are different. They are two separate cars that you can both play with.
Value semantics is a bit like having your own toy car. When you use something with value semantics, you have your own copy of it that you can play with and change as you like without affecting anyone else's copy.
For example, let's say you have a box of crayons. The box contains different colors like red, blue, and green. When you take the box of crayons, you can choose any color you want and use it to draw or color pictures. You can also share your crayons with friends, and they can use their own copy of the crayons without affecting your copy.
In programming, value semantics work in a similar way. When you have a variable with value semantics, you have your own copy of that variable. You can change it or use it in any way you want without affecting other copies of that variable.
For example, let's say you have a variable called "age" that stores your age, which is 5. If you have another friend with a variable called "age," they might also have a value of 5 for their age, but it's their own copy, just like their own toy car.
Value semantics are helpful because they allow us to work with things independently. We can modify our own copies without worrying about how it might affect others. It helps in programming when we want to make changes or perform operations on variables without accidentally changing other variables.
So just like how you can have your own toy car or box of crayons to play with, value semantics give you your own copy of something to work with. It makes things easier and less confusing because you don't have to worry about what other people are doing with their own copies.
