Can someone break down what literals are in programming?

So, 'ABC' in your example is the literal. When you write a value in the code, that's what we call a literal—it literally shows the value. For example, ‘ABC’ doesn’t change. But when you set `Name` to 'ABD', you're not changing 'ABC'; you're assigning a new value to `Name`. Think of a literal as a fixed reference in the code, while the variable `Name` can point to different literals over time.

Literals are essentially the raw values you put directly into your code, like 'ABC' or 3. When you rewrite a variable by using a new literal, you're creating a new instance rather than changing the original literal. So, 'ABC' is literally there in the code as it was written, while `Name` can be changed to point to whatever you want later on.

To clarify, literals are static values you type into your code that don't change. Imagine you define a string as a literal ('hello'). It stays 'hello' unless you write new code. This helps keep the code predictable, and that's why we typically don’t just delete literals in code; they’re constants for a reason!

Great question! A literal can't change once it's been defined in the code, like the number `3` or the string 'XYZ'. If you want to change a literal, you just write new code and replace it. This is important because literals remain the same during the execution of your program, while variables are more flexible. Also, regarding immutability, think of it as a protective measure: literals are meant to stay the same to maintain integrity in your code and prevent accidental changes that could create bugs.
