Why are answers from variable prompts strings in JavaScript no matter what I enter

Question

Every time I enter a specific number, the outputs are shown as strings, as the same type as inputing some text. Why does it works in such way?

Answer 1

As mentioned already, prompt returns a string of text you entered.
Aside from eval(), you can also use Number() and parseInt() for integers and parseFloat() for floating point numbers.
