Comparisons

You’ll often want to compare the value of one variable with another, or the value of a variable against a literal value (i.e., a value typed into the expression). For example, you might want to compare the value of the day of the week to “Tuesday”, and you can do this by checking if todaysDate == "Tuesday" (note that double equal sign). A complete list of comparisons is in Table 1.5.
