Description
JavaScript's alert, confirm and prompt functions are widely considered to be obtrusive as UI elements and should be replaced by a more appropriate custom UI implementation.
Furthermore, alert is often used while debugging code, which should be removed before deployment to production.
Bad Practice
alert("here!");
confirm("Are you sure?");
prompt("What is your name?", "John Doe");
Recommended
customAlert("Something happened!");
customConfirm("Are you sure?");
customPrompt("Who are you?");
function foo() {
const alert = myCustomLib.customAlert;
alert();
}
