JavaScript Assignment #5: Functions

You may do these challenges all together in one file, or in separate files, according to your preference. You will turn them in all together.

Challenge #1: Capitalize

• Declare a function called capitalize that takes one argument, word
• Within the function, capitalize the word
• Return the capitalized word
• When you run console.log(capitalize("hello")) you should get HELLO

Challenge #2: Percentage Calculator

• Declare a function called percentCalc that takes two arguments, amount and percentage
• Return the given percentage of the amount
• When you run console.log(percentCalc(200, 20)) you should get 40

Challenge #3: Divisible

• Declare a function called divisible that takes two argments, dividend and divisor
• Determine whether the dividend is divisible by the divisor (meaning the division will result in a whole number with remainder)
  • Tip: Use the modulo operator
• Return true or false
• When you run console.log(divisble(6, 3)) you should get true
• When you run console.log(divisble(15, 4)) you should get false

Challenge #4: Friend, Enemy

• Declare a function called greeting that takes in two arguments, firstName and status
• Inside the function, write a conditional that determined whether status is the string "friend" or the string "enemy"
• If the person is a friend, return the string that welcomes them by their name
• If the person is an enemy, return a string that tells them to go away
• When you run console.log(greeting("Superman", "friend")) you should get something like Hello Superman!
• When you run console.log(greeting("Lex Luthor", "enemy")) you should get something like Go away Lex Luthor!

Extra challenge (optional)

• What do you think this function should do if the second argument doesn't match "friend" or "enemy"? Think of something fun and implement it!
