Strong typing

Imagine you have a box, and you put something inside it, like a toy car. If you try to take out the toy car, you will get a toy car. This is similar to strong typing.

Strong typing means that when you work with a value or a variable in computer programming, you always know exactly what type it is. Types could be things like numbers, text, or even more complex things like dates or lists.

Just like the toy car example, strong typing ensures that you always get the right thing out of the box. So if you have a variable that is a number, you can be sure that it will always be a number and not suddenly turn into something else.

For example, if you have a variable with the number 5, and you try to add it to another number, like 3, strong typing will make sure that the result is the sum of 5 and 3, which is 8. It won't magically turn into something else.

Strong typing also helps catch mistakes. If you try to add a number and a text together, it will tell you that it's not allowed because they are different types. It's like a helper that keeps you from making errors.

In summary, strong typing is like having a box where you always know what is inside, and it helps prevent mistakes and ensures that you get the right results when working with different types of values in computer programming.
