## Descripción
Compruebe si una cadena (primer argumento, str ) termina con la cadena de destino dada (segundo argumento, target ). Este desafío se se puede resolver con el método .endsWith() , que se introdujo en ES2015. Pero para el propósito de este desafío, nos gustaría que utilices uno de los métodos de subcadena de JavaScript. Recuerda usar la técnica de Leer-Buscar-Preguntar si te atascas. Escribe tu propio código.
## Instrucciones
## Pruebas
```yml
tests:
- text: 'confirmEnding("Bastian", "n") debe devolver verdadero.'

testString: 'assert(confirmEnding("Congratulation", "on") === true, "confirmEnding("Congratulation", "on") should return true.");'
- text: 'confirmEnding("Connor", "n") debe devolver falso.'
testString: 'assert(confirmEnding("Connor", "n") === false, "confirmEnding("Connor", "n") should return false.");'
- text: 'confirmEnding("Walking on water and developing software from a specification are easy if both are frozen", "specification") debe devolver falso.'
testString: 'assert(confirmEnding("Walking on water and developing software from a specification are easy if both are frozen", "specification") === false, "confirmEnding("Walking on water and developing software from a specification are easy if both are frozen", "specification") should return false.");'

- text: 'confirmEnding("If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing", "mountain") debería devolver el valor falso.'
testString: 'assert(confirmEnding("If you want to save our world, you must hurry. We dont know how much longer we can withstand the nothing", "mountain") === false, "confirmEnding("If you want to save our world, you must hurry.

testString: 'assert(confirmEnding("Abstraction", "action") === true, "confirmEnding("Abstraction", "action") should return true.");'
- text: No use el método .endsWith() para resolver el desafío.
testString: 'assert(!(/\.endsWith\(.*?\)\s*?;?/.test(code)) && !(/\["endsWith"\]/.test(code)), "Do not use the built-in method .endsWith() to solve the challenge.");'
