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 our instructions on how to run JavaScript code.
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.

<body>
<script>
function add7(number){
return number + 7;
}
</script>
</body>
</html>Write a function called multiply that takes 2 numbers and returns their product.

<body>
<script>
function multiply(number1, number2){
return number1 * number2;
}
</script>
</body>
</html>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.

<body>
<script>
function capitalize(string){
return string[0].toUpperCase();
}
</script>
</body>
</html>Write a function called lastLetter that takes a string and returns the very last letter of that string:
lastLetter("abcd") should return "d"

<script>
function add7(string){
return string[string.length()-1];
}
</script>
</body>
</html>This is how you write a variable inside a string:
console.log(`It's a tie! You both chose ${humanChoice}.`);This is how you write multiple conditions:
else if (
(humanChoice === "rock" && computerChoice === "scissors") ||
(humanChoice === "paper" && computerChoice === "rock") ||
(humanChoice === "scissors" && computerChoice === "paper")
)
