Why given below code's output is false?

var a=[1,2,3,'hi']; var b=[1,2,3,'hi']; console.log(a == b);

ILLUMINATIE so works it in javascript. Javascript offers no possibility to compare of objects.

That are different objects. The objects are equal as follows. let objectA= {value: 50}; let objectB= objectA; let objectC= {value: 50}; console.log(objectA==objectB; // → true console.log(objectA== objectC); // → false“

A and b are not the same, because if you for example change a to [1,2,3,’hello’] then b would stay the same....

var a=[1,2,3,'hi']; var b=[1,2,3,'hi'] ; console.log(a == b); //false Because it compares refference for Arrays by == opearator. Look this: var a = [1,2,3,'hi']; var b=a, console.log(a == b) ; //true By b=a, now both points same address.

js does not directly compare directly to any object, it will ask for a reference !. here it is right, friends?

Yes, ILLUMINATIE . Array is an object and here javascript up to now compares they references only and not properties of them.
