if(data !== null && data !== '') { // do something }
var myVar=null; if(myVar === null){ //I am null; } if (typeof myVar === 'undefined'){ //myVar is undefined }
if (variable === null) { //Executes only if variable is null but not undefined //Code here } if (variable == null) { //Executes if variable is null OR undefined //Code here }
if (Var === null) { //code goes here }
yes it is!
