Why <input type="number"> format is a text (string)? Not a number?

It's a good question. 👍 I've tried to solve it , but I couldn't. I've added id="inp1" to the first input and then added such string to the body of script: alert(document.getElementById("inp1"). typeof); and it alerted 'undefined'. I'm confused a little. It's very interesting to clear this question for me too!😋☺ I'll try to clear it and if I'll be successful then I'll answer to you here at the post.

I've solved it! There was a mistake in my string. add: id="inp" to the first input. then add such string to the script: alert(document.getElementById("inp").type); It will alert 'number'. So, the type of your inpute type="number" is number.☺😋😋😋😋

@Didi George Danaila I'll try to find out it why. But it's the number 100%. I've checked it with the type.

@Didi Georgel Danaila I found out why it is not worked right. See, the input type is number(we checked it with the type), but when you write such string of code: var firstNumber = document.myForm.firstNumber.value; var secondNumber = document.myForm.secondNumber.value; .value returns the string. So you varriables become string type and afterwards you write such code: var add= firsrNumber + secondNumber; it will do adding as strings. So , you need to add parseInt(as you made already) or Number to change the value of varriables to Number. Is it clear now?
