Assignment #7, part 2 from The Iron Yard's 12-week Front End Engineering bootcamp Q1 2015.
Fun little exercises:
-
Define a function
max()
that takes two numbers as arguments and returns the largest of them. Use the if-then-else construct available in Javascript. -
Define a function
maxOfThree()
that takes three numbers as arguments and returns the largest of them. -
Write a function that takes a character (i.e. a string of length 1) and returns true if it is a vowel, false otherwise.
-
Write a function
translate()
that will translate a text into "rövarspråket". That is, double every consonant and place an occurrence of "o" in between. For example, translate("this is fun") should return the string "tothohisos isos fofunon". -
Define a function
sum()
and a functionmultiply()
that sums and multiplies (respectively) all the numbers in an array of numbers. For example,sum([1,2,3,4])
should return 10, andmultiply([1,2,3,4])
should return 24. -
Define a function
reverse()
that computes the reversal of a string. For example,reverse("jag testar")
should return the string "ratset gaj". -
Represent a small bilingual lexicon as a Javascript object in the following fashion {"merry":"god", "christmas":"jul", "and":"och", "happy":gott", "new":"nytt", "year":"år"} and use it to translate your Christmas cards from English into Swedish.
-
Write a function
findLongestWord()
that takes an array of words and returns the length of the longest one. -
Write a function
filterLongWords()
that takes an array of words and an integer i and returns the array of words that are longer than i. -
Write a function
charFreq()
that takes a string and builds a frequency listing of the characters contained in it. Represent the frequency listing as a Javascript object. Try it with something likecharFreq("abbabcbdbabdbdbabababcbcbab")
.
