Do not submit your solutions to this repo, as any PRs that do so will be closed without merging. **Note**: Due to the way Jest handles failed tests, it may return an exit code of 1 if any tests fail. NPM will interpret this as an error and you may see some `npm ERR!` messages after Jest runs. You can ignore these, or run your test with `npm test exerciseName.spec.js --silent` to supress the errors. diff --git a/pigLatin/solution/pigLatin-solution.js b/pigLatin/solution/pigLatin-solution.js new file mode 100644 index 0000000..259b61b --- /dev/null +++ b/pigLatin/solution/pigLatin-solution.js @@ -0,0 +1,21 @@ +const pigLatin = function (string) { + return string + .split(" ") + .map((word) => { + const index = firstVowelIndex(word); + const beginning = word.slice(0, index); + const ending = word.slice(index); + return `${ending}${beginning}ay`; + }) + .join(" "); +}; + +const firstVowelIndex = function (string) { + const vowels = string.match(/[aeiou]/g); + if (vowels[0] == "u" && string[string.indexOf(vowels[0]) - 1] == "q") { + return string.indexOf(vowels[1]); + } + return string.indexOf(vowels[0]); +}; + +module.exports = pigLatin; diff --git a/pigLatin/solution/pigLatin-solution.spec.js b/pigLatin/solution/pigLatin-solution.spec.js new file mode 100644 index 0000000..cb6e836 --- /dev/null +++ b/pigLatin/solution/pigLatin-solution.spec.js @@ -0,0 +1,56 @@ +const pigLatin = require("./pigLatin"); + +// Topics + +// * modules +// * strings + +// Pig Latin + +// Pig Latin is a made-up children's language that's intended to be confusing. test obeys a few simple rules (below) but when test's spoken quickly test's really difficult for non-children (and non-native speakers) to understand. + +// Rule 1: If a word begins with a vowel sound, add an "ay" sound to the end of the word. + +// Rule 2: If a word begins with a consonant sound, move test to the end of the word, and then add an "ay" sound to the end of the word. + +// (There are a few more rules for edge cases, and there are regional variants too, but that should be enough to understand the tests.) + +// See https://en.wikipedia.org/wiki/Pig_Latin for more details. + +describe("translate", () => { + test("translates a word beginning with a vowel", () => { + expect(pigLatin("apple")).toBe("appleay"); + }); + + test.skip("translates a word beginning with a consonant", () => { + expect(pigLatin("banana")).toBe("ananabay"); + }); + + test.skip("translates a word beginning with two consonants", () => { + expect(pigLatin("cherry")).toBe("errychay"); + }); + + test.skip("translates two words", () => { + expect(pigLatin("eat pie")).toBe("eatay iepay"); + }); + + test.skip("translates a word beginning with three consonants", () => { + expect(pigLatin("three")).toBe("eethray"); + }); + + test.skip('counts "sch" as a single phoneme', () => { + expect(pigLatin("school")).toBe("oolschay"); + }); + + test.skip('counts "qu" as a single phoneme', () => { + expect(pigLatin("quiet")).toBe("ietquay"); + }); + + test.skip('counts "qu" as a consonant even when its preceded by a consonant', () => { + expect(pigLatin("square")).toBe("aresquay"); + }); + + test.skip("translates many words", () => { + expect(pigLatin("the quick brown fox")).toBe("ethay ickquay ownbray oxfay"); + }); +}); diff --git a/snakeCase/solution/snakeCase-solution.js b/snakeCase/solution/snakeCase-solution.js new file mode 100644 index 0000000..bfc3126 --- /dev/null +++ b/snakeCase/solution/snakeCase-solution.js @@ -0,0 +1,19 @@ +const snakeCase = function (string) { + // wtf case + string = string.replace(/\.\./g, " "); + + // this splits up camelcase IF there are no spaces in the word + if (string.indexOf(" ") < 0) { + string = string.replace(/([A-Z])/g, " $1"); + } + + return string + .trim() + .toLowerCase() + .replace(/[,\?\.]/g, "") + .replace(/\-/g, " ") + .split(" ") + .join("_"); +}; + +module.exports = snakeCase; diff --git a/snakeCase/solution/snakeCase-solution.spec.js b/snakeCase/solution/snakeCase-solution.spec.js new file mode 100644 index 0000000..b8620a2 --- /dev/null +++ b/snakeCase/solution/snakeCase-solution.spec.js @@ -0,0 +1,26 @@ +const snakeCase = require("./snakeCase"); + +describe("snakeCase", () => { + test("works with simple lowercased phrases", () => { + expect(snakeCase("hello world")).toEqual("hello_world"); + }); + test.skip("works with Caps and punctuation", () => { + expect(snakeCase("Hello, World???")).toEqual("hello_world"); + }); + test.skip("works with longer phrases", () => { + expect(snakeCase("This is the song that never ends....")).toEqual( + "this_is_the_song_that_never_ends" + ); + }); + test.skip("works with camel case", () => { + expect(snakeCase("snakeCase")).toEqual("snake_case"); + }); + test.skip("works with kebab case", () => { + expect(snakeCase("snake-case")).toEqual("snake_case"); + }); + test.skip("works with WTF case", () => { + expect(snakeCase("SnAkE..CaSe..Is..AwEsOmE")).toEqual( + "snake_case_is_awesome" + ); + }); +});
