Javascript Boolean

Question

I want to know why this is in if condition

var a = new Boolean(false);
if (a) {
alert('hello');
}
else {
alert('world');
}

I think here we are creating a new object which does not depend on argument value so it always returns true unless we assign the value of a to false
am I right? or any other explanation about that?

Answer 1

Any object of which the value is not undefined or null, including a Boolean object whose value is false, evaluates to true when passed to a conditional statement. For example, the condition in the following if statement evaluates to true:

var x = new Boolean(false);
if (x) {
// this code is executed
}
