There are lots of way to check whether the var is array or not but the easiest way is using instanceof Array Example 1 : var myName=[“Vignesh”,”A”,”Sathiyanantham”]; if (myName instanceof Array) { alert(myName is Array!’); } else { alert(‘myName Not an array’); } This will return you myName is Array! Example 2: var myName=”Vignesh A Sathiyanantham”; if (myName instanceof Array) { alert(myName is Array!’); } else { alert(‘myName Not an array’); } This will return you myName Not an Array! You can write a function to make it reusable function ismyvararray(myVar) {  return (myVar instanceof Array); } This will return…
