If you'll recall from our discussion of Storing Values with the Assignment Operator, everything to the right of the equal sign is resolved before the value is assigned. This means we can take the return value of a function and assign it to a variable.
Assume we have pre-defined a function sum
which adds two numbers together, then:
ourSum = sum(5, 12);
will call sum
function, which returns a value of 17
and assigns it to ourSum
variable.
Call the processArg
function with an argument of 7
and assign its return value to the variable processed
.
