En este cap\u00edtulo haremos ejercicios relacionados con strings<\/strong> y expresiones regulares<\/strong>, y son los siguientes:<\/p>\n\n\n\n\n\n\n\n

1. N\u00famero de vocales y consonantes<\/h2>\n\n\n\n

Vamos a programar una funci\u00f3n que dada una cadena de texto, cuente el n\u00famero de vocales y consonantes de dicha cadena.<\/p>\n\n\n\n

      const contarLetras = (cadena = \"\") => {\n        if (!cadena) return console.log(\"No ingresaste una cadena de texto\");\n\n        if (typeof cadena !== \"string\")\n          return console.log(\"No enviaste un string correcto\");\n\n        let vocales = 0,\n          consonantes = 0;\n\n        cadena = cadena.toLowerCase();\n\n        for (let letra of cadena) {\n          if (\/[aeiou\u00e1\u00e9\u00ed\u00f3\u00fa]\/.test(letra)) vocales++;\n\n          if (\/[bcdfghjklmn\u00f1pqrstvwxyz]\/.test(letra)) consonantes++;\n        }\n\n        return console.log({\n          cadena,\n          vocales,\n          consonantes,\n        });\n      };\n\n      contarLetras();\n      contarLetras(5);\n      contarLetras(\"Hola Mundo\");\n      contarLetras(\"bbbbb\");<\/pre>\n\n\n\n
2. Nombre v\u00e1lido<\/h2>\n\n\n\n
Crearemos una funci\u00f3n que valide que un texto sea un nombre v\u00e1lido o no.<\/p>\n\n\n\n
      const validarNombre = (nombre = \"\") => {\n        if (!nombre) return console.log(\"No se ha enviado nada\");\n\n        if (typeof nombre !== \"string\")\n          return console.log(\"El dato enviado no es una cadena de texto\");\n\n        let expReg = \/^[A-Za-z\u00d1\u00f1\u00c1\u00e1\u00c9\u00e9\u00cd\u00ed\u00d3\u00f3\u00da\u00fa\\s]+$\/g.test(nombre);\n\n        return expReg\n          ? console.log(\"El nombre ingresado es v\u00e1lido\")\n          : console.log(\"El nombre ingresado NO es v\u00e1lido\");\n      };\n\n      validarNombre(\"Francisco\");\n      validarNombre(9);<\/pre>\n\n\n\n
3. Email v\u00e1lido<\/h2>\n\n\n\n
Programaremos una funci\u00f3n que valide que igualmente un texto sea un email v\u00e1lido o no.<\/p>\n\n\n\n
      const validarEmail = (email = \"\") => {\n        if (!email) return console.log(\"No enviaste nada\");\n\n        if (typeof email !== \"string\")\n          return console.log(\"No enviaste una cadena de texto\");\n\n        let expReg =\n          \/[a-z0-9]+(\\.[_a-z0-9]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)*(\\.[a-z]{2,15})\/i.test(\n            email\n          );\n\n        return expReg\n          ? console.log(\"Email correcto\")\n          : console.log(\"Email incorrecto\");\n      };\n\n      validarEmail(\"fran@fran.es\");\n      validarEmail();<\/pre>\n","protected":false},"excerpt":{"rendered":"
