 To write our first JavaScript code, we used a built-in function **console.log()**. We passed an argument as input data, and the function displays the output. We passed 'Hello, World' as input data or argument in the console.log() function.
 
 ```js
-console.log('Hello, World!')
+console.log("Hello, World!");
 ```

 As you can see from the snippet code above, _console.log()_ can take multiple arguments. It is recommended to use as many console.log() prints to check what is happening in your code but don't keep all console.log() tests on your code forever. Make your life easy by keeping the browser console open.

 ##### Syntax
 
-Programming languages are similar to human languages. English or many other language uses words, phrases, sentences, compound sentences and other more to convey a meaningful message. The English meaning of syntax is _the arrangement of words and phrases to create well-formed sentences in a language_. The technical definition of syntax is _the structure of statements in a computer language._ Programing languages have syntax. JavaScript is a programming language and like other programming languages it has its own syntax. If we do not write a syntax that JavaScript understands, it will raise different types of errors. We will explore different kinds of JavaScript errors later. For now, let us see syntax errors.

 I made a deliberate mistake. As a result, the console raises syntax errors. Actually, the syntax is very informative. It informs what type of mistake was made. By reading the error feedback guideline, we can correct the syntax and fix the problem. The process of identifying and removing errors from a program is called debugging. Let us fix the errors:
 
 ```js
-console.log('Hello, World!')
-console.log('Hello, World!')
+console.log("Hello, World!");
+console.log("Hello, World!");
 ```
 
 So far, we saw how to display text using the _console.log()_. If we are printing text or string using _console.log()_, the text has to be inside the single quotes, double quotes, or a backtick quotes.
 **Example:**
 
 ```js
-console.log('Hello, World!')
-console.log('Hello, World!')
-console.log(`Hello, World!`)
+console.log("Hello, World!");
+console.log("Hello, World!");
+console.log(`Hello, World!`);
 ```
