Boolean 4/4
Simple Applications of Boolean()
Function
We can pass expressions to the Boolean function to check whether it’s true
or false
. For example, the following code checks if the number passed to the Boolean()
function is completely divisible by 3. It returns true
if the value is completely divisible by 3 and false
otherwise.
1console.log(Boolean(21%3 == 0));
But without Boolean()
we also get the same result. But Boolean function gives more clarity that Boolean value must return.
1console.log(21%3 == 0);
Summary
- Boolean values are either
true
orfalse
. - The first letter of Boolean values (true and false) should be written in uppercase.
- The
Boolean()
method is used to evaluate an expression and returns true or false based on results.
