Why use `return x == 5 ? true : false;`? [closed]

Question

I can not see the advantage of this coding practice. The project I'm working with now is full of these statements so it is not a single mistake.

Another example:

return getNumberOfBooks() > 5 ? true : false; 

And another:

return isRed() ? true : false; 

Answer 1

There is absolutely no reason to do this.

It is redundant and makes the code harder to read.

The following are far easier to read:

return ( getNumberOfBooks() > 5 );  return isRed();
