Is there any harm in adding ( ) in single-line JSX code? I understand that it’s mandatory to wrap multiple lines of JSX elements in ( ) brackets, but I’m in the habit of always starting my JSX with them, as more often than not I’m writing more than one line of code. Is it just bad form?

For example, the compiler does not complain about the following:

// if/else statement begins here:
if (coinToss() === 'heads'){
  (
    img = <img src={pics.kitty} />
  )
}
else {
  img = <img src={pics.doggy} />
}

As you can see I’ve used the ( ) brackets for the first single line of JSX, but not the second in the else statement.
