Christine Gierer 6d9ce1c85c Update description of tests pig-latin.english.md where too vague (#35499 )

* Update description of tests pig-latin.english.md

The last two tests "Should handle words where the first vowel comes in the end of the word." and "Should handle words without vowels." are too vague without examples of what is meant by that.

* Update curriculum/challenges/english/02-javascript-algorithms-and-data-structures/intermediate-algorithm-scripting/pig-latin.english.md

Description

Translate the provided string to pig latin. Pig Latin takes the first consonant (or consonant cluster) of an English word, moves it to the end of the word and suffixes an "ay". If a word begins with a vowel you just add "way" to the end. If a word does not contain a vowel, just add "ay" to the end. Input strings are guaranteed to be English words in all lowercase. Remember to use Read-Search-Ask if you get stuck. Try to pair program. Write your own code.

Instructions

tests:
  - text: <code>translatePigLatin("california")</code> should return "aliforniacay".
    testString: assert.deepEqual(translatePigLatin("california"), "aliforniacay", '<code>translatePigLatin("california")</code> should return "aliforniacay".');
  - text: <code>translatePigLatin("paragraphs")</code> should return "aragraphspay".
    testString: assert.deepEqual(translatePigLatin("paragraphs"), "aragraphspay", '<code>translatePigLatin("paragraphs")</code> should return "aragraphspay".');

    testString: assert.deepEqual(translatePigLatin("eight"), "eightway", '<code>translatePigLatin("eight")</code> should return "eightway".');
  - text: Should handle words where the first vowel comes in the middle of the word.  <code>translatePigLatin("schwartz")</code> should return "artzschway". 
    testString: assert.deepEqual(translatePigLatin("schwartz"), "artzschway", 'Should handle words where the first vowel comes in the end of the word.');
  - text: Should handle words without vowels. <code>translatePigLatin("rhythm")</code> should return "rhythmay".
    testString: assert.deepEqual(translatePigLatin("rhythm"), "rhythmay");

Challenge Seed

function translatePigLatin(str) {
  return str;
}

translatePigLatin("consonant");

Solution

function translatePigLatin(str) {
  if (isVowel(str.charAt(0))) return str + "way";
  var front = [];
  str = str.split('');
  while (str.length && !isVowel(str[0])) {
    front.push(str.shift());
  }
  return [].concat(str, front).join('') + 'ay';
}

function isVowel(c) {
  return ['a', 'e', 'i', 'o', 'u'].indexOf(c.toLowerCase()) !== -1;
}
