In JavaScript, you can use the console.error() method to print a message to the error console. This method takes one or more arguments, and it prints them to the console as an error message.
Here’s an example of how to use the console.error() method:
console.error("This is an error message");You can also use console.log() method to print a message to the console, which is not considered as an error.
console.log("This is a log message");You can also include the variable value with the message you want to print.
var name = "John";
console.error("Name is "+name);You can also use template literals to print the message along with the variable values
var name = "John";
console.error(`Name is ${name}`);It’s important to note that the console.error() method and console.log() method only work when the developer console is open in the browser. So, you should use them for debugging purposes only.
