Looking to alter the behavior of the alert function in TypeScript? You can achieve this by creating a new function that wraps around the original alert and modifies its behavior.
alert = (function (origAlert) {
return function (...messages: any[]) {
origAlert(messages.join(" "))
}
})(alert)
// Example
alert(1, 2)
Attempting to redefine alert(message?: any) may result in an "
" error. It's important to use the original Invalid left-hand side of assignment expressionalert function in your modifications.
To avoid defining an extra variable like const origAlert = alert, you can directly modify the alert function while preserving its original functionality.
If you encounter errors like "
", make sure to test your code in different environments as the behavior may vary.Overload signatures must all be ambient or non-ambient
