Result is shown as string while using node js

Question

0.00/5 (No votes)

See more:

var read=require('readline-sync')

var num1=read.question('Enter first number:')

var num2=read.question('Enter second number')

function sum(num1,num2){
  var total=num1+num2
    console.log('sum of number is :'+total)
}
sum(num1,num2);

What I have tried:

Enter first number:12
Enter second number:32
sum of number is : 1232

Yes, this is exactly what your code is doing as required.
If num1 and num2 must be seen as integers, you must tell it in code.

Inputs are actually strings, not numbers. if you want sum these two numbers
you need to convert into Integer before sum them or convert into integer while
taking input. like:

var num1 = parseInt(read.question('Enter first number:'));
var num2 = parseInt(read.question('Enter second number:'));

OR User the ParseInt method to convert into integer datatype in your Sum method.

var total=parseInt(num1)+parseInt(num2)
