For empty strings you can use !:

var foo = 'yo';
console.log(!foo);

var foo = null;
console.log(!foo);

And for the ? you asked about, it's the Conditional (ternary) Operator, the syntax is condition ? if true : if false you can use it as follows:

var foo = 'yo';
console.log('1 : ' + (!foo ? 'Null' : 'Not Null'));
console.log('2 : ' + (foo === null ? 'Null' : 'Not Null'));
console.log('3 : ' + (foo == null ? 'Null' : 'Not Null'));

var foo = null;
console.log('1 : ' + (!foo ? 'Null' : 'Not Null'));
console.log('2 : ' + (foo === null ? 'Null' : 'Not Null'));
console.log('3 : ' + (foo == null ? 'Null' : 'Not Null'));
