An electricity company is looking at ways of getting meter readings from its customers.
It releases an application for smartphones which allows users to submit their meter reading (a 6 digit number).
JavaScript is used to check that a reasonable value is being entered before a meter reading is sent to a server.
When the user enters a meter reading number, the function validateReading is called.
If the number entered is a valid number between 1 and 999999 inclusive, it returns true otherwise it returns false.
You will need to use the JavaScript function isNaN() standing for “is not a number”. This returns true if the value it is given is not a number and false if it is.
isNaN(computer4) returns true
isNaN(203) returns false
Complete the function
function validateReading(reading)
{
}
