Local scope and functions lesson in JavaScript

JavaScript
#1

My code on local scope and functions is not getting passed. Don’t know what else to do please.

Your code so far


function myLocalScope() {
var myVar = 8;
console.log(myVar);
}
myLocalScope();

console.log(myVar);

Hi and welcome to the forum!

function myLocalScope() {
  'use strict';

  // Only change code below this line

  console.log('inside myLocalScope', myVar);
}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope
console.log('outside myLocalScope', myVar);

You made changes to the starter code above the comment // Only change code below this line. When you change code that you were asked not to change, this can cause the test suite to fail.

Thanks… Noted…
How can I get the starter code back?

#4

There should be a ‘Reset Al Code’ button near the ‘Run the Tests’ button:

It still does not pass. What is being output on the dev console is as follows:

// running tests You should add a local

myVar

variable. // tests completed // console output ReferenceError: myVar is not defined ReferenceError: myVar is not defined

#6

Once you reset the code, did you add back the definition of myVar? What’s your current code?

#7

How can I add my current code here, help.

When you enter a code block into a forum post, you precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

  var MyVar = 5;

}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope
console.log('outside myLocalScope', myVar);

Test error:

You should add a local myVar variable.

Your code:

  var MyVar = 5;

Those sneaky little differences will get you every time

Don’t know what else to do.
MyVar is declared within the function. Think will skip this lesson.

Your capitalization is wrong.
