Let’s write some functions! Write these in the script tag of a skeleton HTML file. If you’ve forgotten how to set it up, review the instructions from Fundamentals Part 1.
For now, just write each function and test the output with console.log.
-Write a function called add7 that takes one number and returns that number + 7. -Write a function called multiply that takes 2 numbers and returns their product. -Write a function called capitalize that takes a string and returns that string with only the first letter capitalized. Make sure that it can take strings that are lowercase, UPPERCASE or BoTh. -Write a function called lastLetter that takes a string and returns the very last letter of that string: lastLetter("abcd") should return "d"
