Understanding the Differences between the freeCodeCamp and Browser Console

Hint:

So were exactly do you run this console.log() command? In order to see the difference between the live console (terminal of freecodecamp) and our browser console we need to open up the console in our browser. Contemporary internet browser have a built in feature called Developer Tools which, among others contains a live console. In this console we can execute Javascript commands and see the result. It behaves in a same manner as the window we write code here in Freecodecamp!

Please follow the instructions provided and copy paste the JS code provided to the example from FCC to your browser's console!

Depending on your browser, in order to open up the Javascript console you need to:

Chrome:

• Click the the following: Menu->More Tools->Developer Tools->Console tab
• or else , for keyboard shortcut: Ctrl + Shift + J (Windows/Linux)

Firefox: 

• Click the the following: Menu->Developer->Web Console
• or else , for keyboard shortcut: Ctrl + Shift + K (Windows/Linux)

Safari:

• Click the the following: Safari->Preferences->Advanced and to the option presented enable: "Show Develop menu in menu bar" Lastly, click: Develop->Show Error Console

Edge:

• Click the the following: ''...'' symbol->Developer Tools-> Console tab

Solution:

// Open your browser console
let outputTwo = "This will print to the browser console 2 times";
// Use console.log() to print the outputTwo variable
console.log(outputTwo);

let outputOne = "Try to get this to log only once to the browser console";
// Use console.clear() in the next line to print the outputOne only once
console.clear();


// Use console.log() to print the outputOne variable
console.log(outputOne);
