Overview ¶

Experiment: calibrate.go Type listing 14.6 into the Go Playground to see it in action: * Rather than passing 5 as an argument to calibrate, declare and pass a variable. Modify the variable and you’ll notice that calls to sensor() still result in 5. That’s because the offset parameter is a copy of the argument (pass by value). * Use calibrate with the fakeSensor function from listing 14.2 to create a new sensor function. Call the new sensor function multiple times and notice that the original fakeSensor is still being called each time, resulting in random values.
