Strong and weak typing

When we say something is "strongly" or "weakly" typed, we are talking about how the computer understands the data or information we are working with.

Imagine you have a toy box with different compartments. When you put your toys away, you need to make sure they go in the right compartment – the one that fits their size and shape.

With "strong typing," the computer is like a toy box with very specific compartments, and each piece of data is labeled with a specific "type" that tells the computer which compartment to put it in. For example, a number might go in one compartment, a letter in another, and a date in yet another. This means that the computer is very particular about what it accepts – it won't let you put a number in the letter compartment or a date in the number compartment.

In contrast, "weak typing" is like a toy box with fewer, more general compartments that can hold many different kinds of toys. The computer is less particular about what goes where, and it's usually more forgiving if you try to put the wrong kind of data in a compartment. It may be able to figure out what you mean, even if you make a mistake.

Overall, both strong and weak typing have their advantages and disadvantages. Strong typing can help catch errors early and make code more robust, while weak typing can make writing code faster and easier. But just like with a toy box, it's important to choose the right approach for the job at hand.
