Prevent use of spacebar when input field is empty

I am making a chat application and i saw that whatsapp doesn't allow the use of space bar when there is no input yet, i did try to find it out in stack overflow itself but they gave the answer which worked only there, but when i tried in my react-app it showed this error: Unexpected use of 'event' no-restricted-globals I am confused what to do, i got this at the first time:

screen shot of the depreciated warning

Then i went to the file and tried commenting the line(not sure if can), but that too didn't work for me. Like is there any other way i can achieve the same functionality without the use event

What is keyhandler defined as? You should define it as function keyhandler(event) but inline it as onKeyDown={keyhandler} with no arguments.

You want to pass in a function to be called, not a specific function call. These are two different things.

The error indicates that event isn't what you think it is, that's resolved to window.event, it doesn't exist like you think it does, because that is now a function call with a static argument instead of the actual event that happened.
