Return vs Log
Return vs Log
A function can log one value and return a different value. The log is for someone reading the console. The return value is what the caller receives.
Read this code:
js
function showInvoiceTotal(total) {
console.log(total * 2);
return total;
}
const result = showInvoiceTotal(12);Your task: Predict the value stored in result and the value written to the console.
Prerequisites
- variables
- operators
- functions
Tests
- predictedReturn matches the value returned to the caller
- predictedLog matches the value printed inside the function
- both predictions are numbers
