Else statement (if its needed?)

JavaScript

Is it possible to create every function without else statement or in some cases it’s needed?

as everything, it depends

can you expand a bit on your doubt?
it is difficult to give an answer without some context

It is sometimes needed.

Can you show me examples of when you need to use else statement?

Obviously a contrived example, but an example of the difference an else makes.

if (age < 21) {
    tooYoungToDrink = true;
}
tooYoungToDrink = false;
// you just served a minor!

if (age < 21) {
    tooYoungToDrink = true;
} else {
    tooYoungToDrink = false;
}
// good job

If you want to do something if some condition is true otherwise do a different thing?? If you don’t put something in an else it always runs – I’m sure you can appreciate that you don’t always want to run code, often you only want it to run if some condition is explicitly met/not met (otherwise don’t run it).
