Introduction to JavaScript – CONSOLE

Introduction to JavaScript – CONSOLE – Before you learn about data types and methods, you need to know how to print values to the console. The console.log() command is a tool that developers use to record the output of their JavaScript programs.

The console.log() command is used to print, or log, text to the console. Consider the following example:

 console.log("Hello!"); 

In this example code above, Hello! is logged to the console. Notice, we denote the end of the line with a semicolon. Although your code will usually run as intended without a semicolon, it is best practice to always include one to ensure your code works as expected in situations when it does need one.

You’ll see in the next exercise that you can put any data type inside the parentheses to print it to the console.

About the Author: Bernard Aybout

In the land of bytes and bits, a father of three sits, With a heart for tech and coding kits, in IT he never quits. At Magna's door, he took his stance, in Canada's wide expanse, At Karmax Heavy Stamping - Cosma's dance, he gave his career a chance. With a passion deep for teaching code, to the young minds he showed, The path where digital seeds are sowed, in critical thinking mode. But alas, not all was bright and fair, at Magna's lair, oh despair, Harassment, intimidation, a chilling air, made the workplace hard to bear. Management's maze and morale's dip, made our hero's spirit flip, In a demoralizing grip, his well-being began to slip. So he bid adieu to Magna's scene, from the division not so serene, Yet in tech, his interest keen, continues to inspire and convene.
