Nice, there is a lot of excellent code here, and you can understand how a code will run before it has run.

Suggested change

	//the function will turn the first given string into Uppercase.
	//the function will turn the first character of a given string into Uppercase.

[PandiSimatupang]

Yes Sir!.. Noted. I should use "the first character" instead of "the first String"

[YoanHlebarov]

For information/reference, when declaring a function we call these parameters, when we call the function we call them arguments. It is a subtle distinction but is important to remember especially when communicating with other developers.

[PandiSimatupang]

Thank you. Noted, I often confuse those both terms.

[YoanHlebarov]

It is important to note that ; [semicolon] is not needed in this case for the function to return when it reaches the return statement. New line is also a valid way to end the line, thus the function will not execute a + b even if we were missing a ;.

[PandiSimatupang]

Thanks, I used to think that a semicolon marked is the end of a statement, but now I know that a newline (\n) can also signify the end.

Can you wrap your code into a function that is then called with the argument "hello world I am sleepy"?

[YoanHlebarov]

@PandiSimatupang The requirements for the Sprint-2/3-mandatory-implement/2-cases.js are not yet met. Make sure you create a function that can be used to manipulate a string that we pass to it.

Creating functions can help us reuse code we may find useful often. This has two benefits - 1st it allows us to clearly identify what happens if we have a good function name (eg stringToUpperCase()), 2nd if we ever need to modify the behaviour of this code, we only need to do it once - in the function, if you used the same code in many places you will have to modify it in many cases. We call this Technical Debt and this can become a serious issue that can have a real world implications to a business.
