Thank you mike! I have learnt SQL and javascript through you and I have been able to get a job!

[DevlogBill]

Very good video! If you ever programmed in Python, you have the input which is the same as window.prompt and you have print which is the same as document.write. So basically, you're the only YouTube when asked how do you perform input for JavaScript, no one couldn't explain? Thank you for showing me this method now I can perform similar task with JavaScript as I do with Python.

Good tutorials. Excellent. Do you know Wordpress plugin development?

[MalkiaMmoja]

Thank you for another awesome tutorial.

I believe (num1 + num2 * 1) also forces the variables to be numbers rather than strings.

This is fine and all but what about if you dont want to use a window promt and you want to use html input box?

[jackfukin]

Will it be the same if you want the user to enter the order of operations like in multiplying division and subtraction or average.

[swapnapatil]

I'm getting a message of window not defined for user input. please help me sir

[paulorodrigolimafigueiredo]

I love your tutorials

Instead change the variables values on line 5 and 6, you could write like that:

document.write(Number(num1) + Number(num2));

It's better cause accept any type of number (float, int...)

[denisivombo]

thank you can make a code js to calculate the age according to the current year

[stablehealth]

num1 = Number(num1)
num2 = Number(num2)

It’s not playing. It says “something went wrong. Tap to retry” even after retrying it says the same thing.
