To hide JavaScript errors from the browser, you can use the function suppressJSError(). This function helps keep any JavaScript errors from appearing on the webpage, as shown in the code below.

This is often used in production to hide non-critical JavaScript errors from users or to prevent minor errors from cluttering the console. However, it’s generally discouraged to suppress all errors, as this can make debugging more difficult by hiding potential issues in the code.

Complete Code

function suppressJSError() {
  return true;
}
window.onerror = suppressJSError;

Explanation:

  1. Function suppressJSError: This function, suppressJSError, is defined to always return true. In the context of JavaScript error handling, returning true indicates to the browser that the error has been handled and should not be reported to the console.
  2. Assigning suppressJSError to window.onerror:
    • The window.onerror property is an event handler that gets triggered whenever an error occurs during the execution of JavaScript code on the page.
    • By assigning suppressJSError to window.onerror, you are instructing the browser to call this function each time an error happens. Since suppressJSError always returns true, any JavaScript error will be suppressed and won’t appear in the console.

This is often used in production to hide non-critical JavaScript errors from users or to prevent minor errors from cluttering the console. However, it’s generally discouraged to suppress all errors, as this can make debugging more difficult by hiding potential issues in the code.
