Remember that `&&` is an operator that returns the value of the first falsy operand from left to right, and if all are truthy you get the value of the last operand. So if `a.length` is `0` then it'll return `0`. React is happy to render `0`. I strongly recommend to people not to use `&&` for this reason. Use a ternary `? :` and handle both case!
