This is happening because when the page loads the modal isVisible property is undefined. Maybe it does not have a default value. @keyurparalkar do you know what can be the implications of setting a default value on this prop

@somangshu if the value is set to undefined then shouldn't it come as false?

[somangshu]

@dilippitchika the value right now if undefined after the eval cycle. Since our output is undefined the issue occurs. undefined and false are different type / value.

Both undefined and null are falsy by default. So == returns true. But when we use the strict equality operator (===) which checks both type and value, it returns false
