Break y continue"},"content":{"rendered":"\n

En cap\u00edtulos anteriores ya hab\u00edamos visto el uso de estructuras de control<\/strong> como condicionales<\/strong> y ciclos<\/strong>, y cuando est\u00e1bamos trabajando con el uso de la instrucci\u00f3n switch… case<\/em><\/strong>, en cada uno de los casos ten\u00edamos para romper dichos casos, la palabra break<\/em><\/strong>, que lo que  hace es salir de la estructura (en este caso el switch<\/em><\/strong>) para no estar leyendo todos los casos.<\/p>\n\n\n\n\n\n\n\n

En este cap\u00edtulo vamos a ver para que se utilizan las palabras break<\/em> <\/strong>y continue<\/em><\/strong>. Estas palabras nos ayudan a controlar m\u00e1s el flujo de nuestras estructuras de control<\/strong>, sobre todo si estamos en un bucle<\/strong> y a lo mejor, necesitemos llegar a cierto n\u00famero de repeticiones, y cuando lo hagamos, salirnos de la ejecuci\u00f3n del c\u00f3digo o, a veces, s\u00f3lo saltarnos ciertas vueltas a un bucle en base a un patr\u00f3n. Por ejm, que de una lista s\u00f3lo queramos imprimir los n\u00fameros pares o impares, para ello nos puede ayudar break<\/em> <\/strong>o continue<\/em><\/strong>.<\/p>\n\n\n\n

Ejm<\/strong><\/p>\n\n\n\n

        const numeros = [1,2,3,4,5,6,7,8,9,10];\n\n        for (let i = 0; i < numeros.length; i++) {\n            if (i === 5) {\n                break;\n            }\n            console.log(numeros[i]);\n        }<\/pre>\n\n\n\n
Lo que hace el ejm de arriba es que cuando llega al 5, detiene la ejecuci\u00f3n del c\u00f3digo y se sale del bucle.<\/p>\n\n\n\n
Ejm<\/strong><\/p>\n\n\n\n
        const numeros = [1,2,3,4,5,6,7,8,9,10];\n\n        for (let i = 0; i < numeros.length; i++) {\n            if (i === 5) {\n                continue;\n            }\n            console.log(numeros[i]);\n        }<\/pre>\n\n\n\n
Mientras que con la palabra reservada continue<\/em> <\/strong>lo que hace  es saltarse esa condici\u00f3n y contin\u00faa ejecutando el c\u00f3digo del bucle.<\/p>\n","protected":false},"excerpt":{"rendered":"
