The automatic message a user gets when inputting an invalid response into a .questionInt('Type a number') when using node.js readline-sync module
'a'
Input valid number, please.
How do I change the response from 'Input valid number, please.' to 'This is not a number'?
here's part of the code:
function numberOne() {
firstNumber = readline.questionInt('Please enter the first number: ');
if (isNaN(firstNumber)) {
console.log('This is not a number');
numberOne();
}
}
function numberTwo() {
secondNumber = readline.questionInt('Please enter the second number: ');
if (isNaN(secondNumber)) {
console.log('This is not a number');
numberTwo();
}
}
I tried to remove the 'Int' from the question, and it worked, however, then the calculator wouldnt properly calculate the operations. 1+1=11. SO I think that means it just considered it a string. SHould I just add code to change back to a number after or something?
