choice = input.questionFloat('\t1. Display all members\' information \n\t2. Display member information \n\t3. Add new member \n\t4. Update points earned \n\t5. Statistics\n\t6. Exit \n\t>> ');
if (choice.toString().includes('.')) {
console.log ('Please enter a valid input.');
}
choice contains the input from the user. If choice is a floating number, it will prompt the user that it is a invalid input. If there a better way of doing this instead of using .includes?
You can do that easily with JavaScript.
First take and convert to number and check if it's truthy value (non NaN) and check if it's not integer.
const num = Number('123.3')
if (num && !Number.isInteger(num)){
//float
}
Why not compare it to its value in int?
const intValue = 12
console.log(parseInt(value) !== value) // false => is an int
const floatValue = 12.1
console.log(parseInt(value) !== value) // true => is not an int
