Javascript help

[Peeeeeeeeeeynk]

Hi I'm practicing javascript at the moment,I'm doing these problems where I found on the internet where you have to code a program that does the follwoing.

 

I managed to get  the first one by using an if else but when I tried the if else again on the other numbers it did not work.

 

Any help?

I'm really new to javascript.

 

Determine whether the following expressions are true or false:

1. !true || !false

2. (true && !false) && (false || !true)

3. (4 > 5) || true

4. ("this" != "that") && ("zebra" > "aardvark")

5. ((4 >= 6) || ("grass" != "green")) && !(((12 * 2) == 144) &&

true)

you don't need any if or else statement to solve this. In fact you don't need to program anything to solve those exercises ...

Also, javascrpt if/else seems to work just fine for all of these problems as far as I tested

sure. Those are all logical/boolean expressions that evaluate to an boolean value, which is needed in an if-then-else-statement

I know you can mentally solve them but the problem asked me to do a piece of code to prove if they are true or false 

.sorry should have mentioned that in the post

I'm still new to javascript maybe my syntax sucks.

var x = !true || !false;console.log(x)var y = ((4 >= 6) || ("grass" != "green")) && !(((12 * 2) == 144) && true);console.log(y)

var x = !true || !false;console.log(x)var y = ((4 >= 6) || ("grass" != "green")) && !(((12 * 2) == 144) && true);console.log(y)
