Control Structures in JavaScript

  Control Structures in javascript allow you to manage the flow of a program, making decisions and repeating actions as needed.

Types of Control Structures

  javascript has different types of Control Structures:

• Conditionals: Allow you to make decisions based on a condition.
  • if: Executes a block of code if a condition is true.
  • if-else: Provides an alternative when the condition is false.
  • else if: Allows evaluating multiple conditions.
  • switch: Selects among multiple possible cases.


• Loops: Allow you to execute a block of code repeatedly.
  • for: Used when you know the exact number of iterations.
  • while: Executes a block as long as a condition is true.
  • do-while: Similar to while, but ensures at least one execution.
  • for...in: Iterates over the properties of an object.
  • for...of: Iterates over elements of iterable objects like arrays.


• Error handling: Captures and handles errors in the code.
  • try: Defines a block of code that may throw an error.
  • catch: Handles the error thrown in the try block.
  • finally: Executes a block of code, regardless of the result.

Usage Example

  A practical example of a conditional control structure:

let edad = 18;

if (edad >= 18) {
  console.log("Eres mayor de edad.");
} else {
  console.log("Eres menor de edad.");
}

  This example shows how to make a decision based on the age variable.
