If you are working on the Web Development Process on any Web Console or Web Browser, you should use a Debugging Tool that will greatly help the process. The “Console Object in JavaScript” is one such important debugging tool.
If you are naive in the Web Development Process, you might have heard about the JavaScript Console only as a tool to print values on the Web Page or Web Browser. But the JavaScript Console Object is way more efficient than you think.
This article will discuss all the information related to the Console of JavaScript and different JavaScript Console Methods present or used highly by Web Developers. So, let us start our discussion.
Still, if you have any doubts related to JavaScript homework then you can hire the best experts from CodingZap.
Summary or Key Highlights:
The Browser Console is a popular tool used for the Debugging Purposes of JavaScript.
The Console of JavaScript can be found in the Developer Tools in every web browser.
Many different Console Methods can be used in a JavaScript Code.
Console Logs are one of the most important functions used for the Printing Purposes.
The JavaScript Consoles can be used for the Doctype HTML Document as well.
What Is Console Object? Read Below
If you are learning JavaScript for the first time, you must come across the concept of the Console Log in JavaScript. And from the learning, you concluded that it is the process needed in JavaSript for printing the statements.
However, it is the half-truth that you know. The JavaScript Console Object is used for the Debugging Process as well. It is present in all the Developer Tools of any Web Browser. The Console can be assumed as the Shell where different commands can be executed.
On the Console, one can execute any existing HTML Document along with making the Stack Trace of DOM, any Web Page, etc. Using the Console, you can Inspect any JavaScript Element using some simple commands. From all such perspectives, the Console Logs are very important.
Where Is JavaScript Console In Chrome?
We are saying that the Console Log in JavaScript is present in all Web Browsers. Google Chrome is one of the best browsers that all individuals work with. So, where is the JavaScript Console present for the Chrome Web Browser?
Suppose you want to use the Chrome Browser as your primary application to run the JavaScript Expressions. In that case, the knowledge to open the JavaScript Console in the Chrome Browser becomes very important. There are two methods to open the Console of JavaScript in Chrome.
Method 1: Use Keyboard Shortcut
In this process, you must just press some Simple Keys in the Keyboard. You have to press three keys simultaneously. The Three Keys are the Control (CTRL) + Shift + J. If you press these keys at a time on any webpage, the Console will be opened.
Method 2: Using The More Option
Now, if you don’t want to rely upon the Keyboard Shortcut, then there is a broad way also present. On any Web Page, you have to click on the Three Dots of Chrome. Now, Scroll Down to find the More Tools option.
Under the More Tools, you will get the option as the Developer Tools. Open the section & go to the Console Option. However, the best way will be to use the Keyboard Shortcut without any problem.
How Many Types Of Console In JavaScript?
Now, it is time to move ahead in the Practical Implementation Process of the Console for JavaScript. In JavaScript, many functions can be used with the Console to complete any certain operation. Here, we are going to discuss some important info on them.
We are going to make a List of the Console Programs that you should use multiple times in your JavaScript Code. So, let us have a look at the following list of operations.
Console Log
Console Error
Console Warning
Console Information
Console Debugging
Console Clear
Console Table
Console Group
How To Implement Different JavaScript Console Methods
Now, till this point, all the theoretical knowledge regarding the Console of JavaScript should be cleared. Now, it is time to move to some practical practice. Whatever the methods are mentioned above, we are going to implement them.
We are going to start with the Console Log which is the most important function used in JavaScript from the basics. After that, we are going to discuss some relatively advanced topics used in the Console of JavaScript.
1) Console Log Function:
The Console Log Function is a very basic & simple function that you all know about. From Day 1 in JavaScript, most of the students think that Console Log is the process of Print Statements in JavaScript. But, the Print Statement is something different.
However, indeed, the Console Log in JavaScript can also be used to print the value. You can print any Integer, String, Float, etc using the Console Log function. But first, we have to look at the Syntax of the process.
General Syntax: console.log();
// Print A Log Regular Message
console.log("Printing CodingZap Message");
Output:
From the above output, we can see that the Statement given to the Console Log is getting printed on the Console Output. So, we can say that the Console Log can be used to print the statement into any JavaScript Program.
2) Console Error Messages Function:
Now, after the Console Log, it is time to go to Print the Error Message. Please make a note that, it is not printing the Warning Message, it is printing the Error Message. While you work on any programming language, you should have noticed that the Compiler gives Error Message.
It is the same kind of process. If you want to prompt an Error on the Call Path, you should use the system. Here, instead of the Console Log, we will use a different approach. To do understand, let us check the Syntax of it.
General Syntax: console.error();
// Print An Error Statement
console.error("Printing CodingZap Error Message");
Output:
From the above output, we can see that the Message provided in the box is getting printed on the Console with the Error Symbol. So, the Error Statement is executing properly without having any issues. In this case, no Alert Box will be used at all.
3) Console Warning Message Function:
Now, let us further extend to another important messaging service. Along with the Error, there is another message service present. That is known as the Warning Statement. In this case, we are going to implement the Warning Statements in the Console.
The Implementation of Warning Statements is more similar to the Error Statements. There is a good syntax similarity also exists between Warning & Error Statements. Let us have a look at them from the Syntax itself.
General Syntax: console.warn();
// Print A Warning Message
console.warn("Printing CodingZap Warning Message");
Output:
As you can see from the output, the Statement is getting printed on the screen along with a Yellow Line. This is the symbol that the Warning Statement is getting executed. So, the above-mentioned warning program works completely fine.
4) Console Information Message Function:
Now, after Error & Warning Statements, it is time to focus on the Information Statements as well. If you are going to display some information, then such a process can be used. You might think that it is the same process as the Console Log.
You are correct in this case. The Console Log & Console Info are two functions whose workings are completely the same. However, it is used to make a difference between simple Printing & Information Printing in JavaScript.
General Syntax: console.info();
// Printing An Informational Message
console.info("Printing CodingZap Info Message");
Output:
From the above output, we can see the Message that is given in the Information Function is getting printed on the screen. And from the Output, you can’t differentiate between the Console Log & Console Info. So, the program is executed successfully.
5) Browser Debugging Console Message:
Now, after a lot of statement printing process, it is time to focus on the Debugging Processes as well. In the JavaScript Program Console, there is a special feature for the Debugging Process. In that case, the statement doesn’t get printed on the screen.
You can use the process on the Console to highlight any statement where the problem is arising. It is like a process to comment on the process. Let us check the syntax of the Console Debugging Method of JavaScript.
General Syntax: console.debug();
// Printing Debug Message
console.debug("Printing CodingZap Debug Message");
Output:
From this output, we can see that, there is nothing printed on the scene. Hence, the working of the Debugging Command is going completely fine. However, you can notice that the JavaScript Program has ended without any printing.
6) Clear Console Output Screen:
Now, if you are working with us till this point, no doubt that there is a lot of information stored on your Console. And the Console is itself looking very ugly. So, if you want to clean the Console, you are thinking of relaunching it.
However, there is no need to relaunch the Console in case you want to make it clear. If you want to Clear the Console, you can use the Clear Command with the Console. Let us have a look at the general syntax of the Console to Clear.
General Syntax: console.clear();
// Clearing The Console
console.clear();
Output:
From the above output, you can see that there are nothing is printed on the screen. However, there is a message present as “Console Was Cleared”. So, the Clear Command of the Console is working properly and has removed everything from the output.

Conclusion:
In the end, we can say the “Console Object in JavaScript” is very important to learn.
The Console is a very simple topic from where you can start your JavaScript Journey. Also, the concept is not that much of complicated as others. So, we will recommend understanding the concept very well before moving on to any other advanced topic.
Also if you are working towards becoming a better JavaScript developer you can read javascript and jquery for front end web development.
