Lambda Serialization : Explain this to me like I am a 5-year old child

How I would describe Lambda Serialization, in the context of my favorite thing: FOOD

Imagine you have a special chef (like a lambda expression) who knows how to make a sandwich in a very specific way. Now, you want to save the chef’s sandwich-making recipe so that if you ever need it again, you can use it to make the same delicious sandwich.

Here’s how it works:

1. Chef (Lambda Expression): This chef knows how to make a peanut butter and jelly sandwich.
2. Write Down the Recipe (Serialize): You write down the step-by-step recipe for making the sandwich on a piece of paper.

• Step 1: Take two slices of bread.
• Step 2: Spread peanut butter on one slice.
• Step 3: Spread jelly on the other slice.
• Step 4: Put the slices together.

3. Save the Recipe (Save the File): You put the piece of paper with the recipe in a recipe box.

4. Read the Recipe (Deserialize): Later, you take the piece of paper out of the recipe box.

5. New Chef (New Code): You give the recipe to another chef, and this new chef follows the same steps to make the exact same peanut butter and jelly sandwich.

So, in this food example:

• The chef is like a lambda expression. It’s a small part of your cooking knowledge that knows how to make a specific dish.
• Writing down the recipe is like serialization. You’re taking the chef’s knowledge and putting it on paper.
• Saving the recipe in the recipe box is like saving the serialized data to a file or cache.
• Reading the recipe later is like deserialization. You’re getting the saved instructions.
• A new chef using the recipe is like a new piece of code using the deserialized lambda expression to do the same task.

In the world of programming, we use lambda expressions to write small, specific pieces of code (like making a sandwich), and serialization helps us save these pieces of code so we can reuse them later, even if the program has been turned off and on again.
