Hi Steven,

That is correct, in most languages boolean values can be evaluated without the need for an equality operator as the compiler will do that for us, however unless you know explicitly that value will always been either true or false it's common practice to use the triple equals === operator as that ensures that both the left and right values of the operator are equal to the same type and value rather than just comparing the value by itself, ie:

// This will only work if $some_variable evaluates as truthy value.
if ($some_variable === true)
