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?

Question

declaring variables

Answer 1

yes

Answer 2

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
