Alert(1) not working in typescript

alert(1) is not working in typescript

Alert actually popup the screen to show the particular message @jainmayank373

Can you show me the sample script you have? May be the code is not reaching to that particular line while executing,

If you see some browsers like Tableau web data connector, they won’t display the alert message, instead they will write the logs in their log files whenever we run the script as simple as log4s do in the JAVA code
