Condicionales (if, else, switch)<\/em><\/h2>\n\n\n\n

Condicionales if y else<\/strong> Las declaraciones condicionales if<\/code> y else<\/code> permiten que tu programa tome decisiones basadas en condiciones. Un bloque de c\u00f3digo dentro de un if<\/code> se ejecuta si la condici\u00f3n es verdadera; en caso contrario, se puede proporcionar un bloque de c\u00f3digo else<\/code> para ejecutar si la condici\u00f3n es falsa.<\/p>\n\n\n\n

Ejemplo: let edad = 18;if (edad >= 18) {  console.log(\u00abEres mayor de edad.\u00bb);} else {  console.log(\u00abEres menor de edad.\u00bb);}<\/p>\n\n\n\n

Switch<\/strong> La instrucci\u00f3n switch<\/code> es \u00fatil cuando tienes m\u00faltiples casos y deseas ejecutar diferentes bloques de c\u00f3digo seg\u00fan el valor de una variable.<\/p>\n\n\n\n

Ejemplo: let diaSemana = \u00abLunes\u00bb;switch (diaSemana) {  case \u00abLunes\u00bb:    console.log(\u00abEs el primer d\u00eda laborable.\u00bb);    break;  case \u00abViernes\u00bb:    console.log(\u00ab\u00a1Por fin es viernes!\u00bb);    break;  default:    console.log(\u00abEs un d\u00eda cualquiera.\u00bb);}<\/p>\n\n\n\n

Bucles (for, while)<\/em><\/p>\n\n\n\n

Bucle for<\/strong> Un bucle for<\/code> se utiliza para repetir una serie de instrucciones un n\u00famero espec\u00edfico de veces. Puedes usarlo para recorrer arreglos, realizar c\u00e1lculos repetidos, etc.<\/p>\n\n\n\n

Ejemplo: for (let i = 0; i < 5; i++) {  console.log(\u00abIteraci\u00f3n \u00bb + i);}<\/p>\n\n\n\n

Bucle while<\/strong> El bucle while<\/code> se repite mientras una condici\u00f3n sea verdadera. Es \u00fatil cuando no sabes cu\u00e1ntas veces se repetir\u00e1 el c\u00f3digo.<\/p>\n\n\n\n

Ejemplo: let contador = 0;while (contador < 3) {  console.log(\u00abIteraci\u00f3n \u00bb + contador);  contador++;}<\/p>\n\n\n\n

Instrucciones de salto (break, continue)<\/em><\/p>\n\n\n\n

break<\/strong> La instrucci\u00f3n break<\/code> se utiliza para salir de un bucle o de una instrucci\u00f3n switch<\/code> antes de que se complete. Puedes usarla para detener un bucle cuando se cumple una condici\u00f3n.<\/p>\n\n\n\n

Ejemplo: for (let i = 0; i < 5; i++) {  if (i === 3) {    break;  }  console.log(\u00abIteraci\u00f3n \u00bb + i);}<\/p>\n\n\n\n

continue<\/strong> La instrucci\u00f3n continue<\/code> se utiliza para saltar una iteraci\u00f3n en un bucle. Puedes usarla cuando deseas omitir parte del bucle bajo ciertas condiciones.<\/p>\n\n\n\n

Ejemplo: for (let i = 0; i < 5; i++) {  if (i === 2) {    continue;  }  console.log(\u00abIteraci\u00f3n \u00bb + i);}<\/p>\n\n\n\n

Ejercicio Pr\u00e1ctico<\/em><\/p>\n\n\n\n

Aqu\u00ed tienes un ejercicio para que los lectores practiquen las estructuras de control. Crea un programa que cuente y muestre en la consola los n\u00fameros pares del 1 al 10. for (let i = 1; i <= 10; i++) {  if (i % 2 === 0) {    console.log(i + \u00bb es un n\u00famero par.\u00bb);  }}<\/p>\n\n\n\n

Este ejercicio permite a los lectores aplicar condicionales y bucles para resolver un problema pr\u00e1ctico.<\/p>\n\n\n\n

Resumen<\/em><\/p>\n\n\n\n

En este cap\u00edtulo<\/a>, hemos explorado las estructuras de control en JavaScript, incluyendo condicionales (if, else, switch), bucles (for, while) y las instrucciones de salto (break, continue). Estas estructuras son esenciales para tomar decisiones en un programa y para repetir tareas de manera eficiente. El ejercicio pr\u00e1ctico proporcionado ayudar\u00e1 a los lectores a aplicar y consolidar lo que han aprendido sobre estas estructuras de control. En el siguiente cap\u00edtulo, continuaremos profundizando en la programaci\u00f3n<\/a> con JavaScript.<\/p>\n","protected":false},"excerpt":{"rendered":"
