Do I need to declare a var in the js file to validate data entered in a linked html form? Have you filmed a video dealing with this type of validation? Thanks!

[trialdy_khs]

how about we want to use 'console.log' instead of 'document.write'?

[natnaelteshome]

did this concept changed in 2019? Sarah did display on my webpage even though I entered name2 inside document.write which was outside the function?
var name="Henry" ;

function printName () {

name2="Sarah";
}
printName () ; // call function

document.write(name2) ;

U said that If we don't prefix 'var' for a variable inside a function, it will be treated as global variable. So we can access that variable outside the function as well. But that not working ☹️. Where I have gone wrong. If someone can explain, I'll be glad

[deborahbrown]

This didn't work for me at all.
I don't know why.
