Can variables be declared on a single line e.g, var a, b, c, d, rather than var a, var b, var c, var d, on four separate line?

You can, but with coma as separator, you must put the keyword 'var' once.... You can do ( wich is equivalent ) var a; var b; var c; /* or */ var a, b, c;; ... and with affectation: var a; var b=42; var c; /* or */ var a, b=42, c;; // a and c are juste declared, not initialized
