En estos primeros ejercicios estamos manejando cadenas de texto<\/strong> y como podemos manipularlas. Comencemos a resolver los ejercicios:<\/p>\n\n\n\n\n\n\n\n

1. Invertir palabras<\/h2>\n\n\n\n

Vamos a programar una funci\u00f3n que invierta las palabras de una cadena de texto.<\/p>\n\n\n\n

      const invertirCadena = (cadena = \"\") => {\n        !cadena\n          ? console.log(\"No ingresaste una cadena\")\n          : console.log(cadena.split(\"\").reverse().join(\"\"));\n      };\n\n      invertirCadena(\"Hola Mundo\");<\/pre>\n\n\n\n
2. N\u00famero de veces que se repite una palabra<\/h2>\n\n\n\n
Vamos a programar una funci\u00f3n que cuente el n\u00famero de veces que se repite una palabra.<\/p>\n\n\n\n
      const textoEnCadena = (cadena = \"\", texto = \"\") => {\n        if (!cadena) return console.log(\"No ingresaste una cadena\");\n\n        if (!texto) return console.log(\"No ingresaste un texto a evaluar\");\n\n        let i = 0,\n          contador = 0;\n\n        while (i !== -1) {\n          i = cadena.indexOf(texto, i);\n          if (i !== -1) {\n            i++;\n            contador++;\n          }\n        }\n\n        return console.log(`La palabra \"${texto}\" se repite ${contador} veces`);\n      };\n\n      textoEnCadena(\"Hola Mundo Mundo, Adi\u00f3s Mundo\", \"Mundo\");<\/pre>\n\n\n\n
3. Pal\u00edndromo<\/h2>\n\n\n\n
Vamos a programar una funci\u00f3n que valide si una palabra o frase es un pal\u00edndromo<\/strong> (se lee igual en un sentido que en otro)<\/p>\n\n\n\n
      const palindromo = (palabra = \"\") => {\n        if (!palabra) return console.log(\"No ingresaste una palabra o frase\");\n\n        palabra = palabra.toLowerCase();\n\n        let alReves = palabra.split(\"\").reverse().join(\"\");\n\n        return palabra === alReves\n          ? console.log(\n              `S\u00ed es pal\u00edndromo. Palabra original ${palabra} - Palabra al rev\u00e9s: ${alReves}`\n            )\n          : console.log(\n              `No es pal\u00edndromo. Palabra original ${palabra} - Palabra al rev\u00e9s: ${alReves}`\n            );\n      };\n\n      palindromo(\"Salas\");\n      palindromo(\"Francisco\");<\/pre>\n\n\n\n
4. Eliminar cierto patr\u00f3n de caracteres<\/h2>\n\n\n\n
Vamos a programar una funci\u00f3n expresada que elimine cierto patr\u00f3n de caracteres de un texto dado<\/p>\n\n\n\n
      const eliminarCaracteres = (texto = \"\", patron = \"\") => {\n        !texto\n          ? console.log(\"No ingresaste un texto\")\n          : !patron\n          ? console.log(\"No ingresaste un patr\u00f3n de caracteres\")\n          : console.log(texto.replace(new RegExp(patron, \"ig\"), \"\"));\n      };\n\n      eliminarCaracteres();\n      eliminarCaracteres(\"x1, x2, x3, x4\", \"x\");<\/pre>\n","protected":false},"excerpt":{"rendered":"
