@Vapi explain blocks to me

@jmadarieta3 Blocks in programming are a way to group multiple statements together to create a single compound statement. They are typically enclosed within curly braces

{}

in many programming languages. Blocks define a scope for variables and functions, meaning that variables declared within a block are usually not accessible outside of it. Here's an example in a pseudo-code:

{
    // Start of the block
    int x = 10;
    int y = 20;
    int sum = x + y;
    // End of the block
}

In this example,

x

,

y

, and

sum

are variables that are scoped within the block. They are created when the block is entered and typically cease to exist when the block is exited. Blocks can be used in various contexts, such as: - **Control Flow Statements**: In

if

,

else

,

while

,

for

, and other control structures, blocks define what code should run based on certain conditions or loops.

if (condition) {
      // Block for the 'if' statement
  } else {
      // Block for the 'else' statement
  }

- **Function Definitions**: Blocks are used to define the body of functions, encapsulating the logic that should be executed when the function is called.

function myFunction() {
      // Block defining the function body
  }

- **Try-Catch-Finally**: In exception handling, blocks are used to separate the code that might throw an exception, the code that handles the exception, and the code that should run regardless of whether an exception occurred.

try {
      // Block of code to try
  } catch (exception) {
      // Block of code to handle errors
  } finally {
      // Block of code to be executed regardless of the try / catch result
  }

Blocks are fundamental to structuring code in a readable and maintainable way, allowing developers to organize their code logically and control the flow of execution.
