# What is a console.log in JavaScript?

The **console.log()** method is mainly used for debugging in **JavaScript**. It outputs a message to the web console. All modern web browsers provides support for it. 

## 1. Strings
You can write anything to the web console by passing it as a string. For example,

![console.log string example](https://cdn.hashnode.com/res/hashnode/image/upload/v1646039093729/r1KBcKolJ.png)

This will print **I am here** to the web console of the browser you are using. Here is the screenshot of the output when run in the [JavaScript replit](https://replit.com/languages/nodejs)

## 2. Variables
In addition to strings, you can log variables to inspect their values in the web console. Referring to our sum example, we can inspect the values of individual variables or all the variables.

It will print **10** for a and **20 30** for b and sum.

You can log strings and variables together in the web console.

## 3. Objects
While working with APIs, you may need to inspect the value of any object returned in a JSON response. You can log it to the web console.
