- This program is very simple, the trick is to understand what a boolean primitive is. The programs requires a true or false answer.
- You will need to check for the type of the parameter to see if it is a boolean.
- To check for the type of a parameter, you can use
typeof
- Since you must return true or false you can use if statements or just have it return the boolean used for the if statement.
Solution ahead!
function boo(bool) {
// Uses the operator typeof to check if is a boolean
// if yes then return true, if it is another type then return false
return typeof bool === 'boolean';
