JavaScript problem

Question

Why this doesn't works 😭
var Input1 = prompt("Please enter the first input:","");
var Input2 = prompt("Please enter the second input:","");
var answer = Input1 + Input2;
function add() {
alert("The answer is: " + answer);
};
Where's the problem?

Answer 1

Just convert the prompt from string to Number ..
This is the solution by using Number() function to make any string to number that is supported....
Here is the code :

var Input1 = Number(prompt("Please enter the first input:",""));
var Input2 = Number(prompt("Please enter the second input:",""));
var answer = Input1 + Input2;
function add() {
alert("The answer is: " + answer);
};

Answer 2

In addition to ODLNT ,Prompt function can take two parameter, (message, default value [string]), so if you want to calculate sum of two numbers before anything it's important to convert the input values to numbers. Else if you want to concatenate two string it's all find.

Answer 3

You didn't invoke the add function.
add()
