Analyze the following code: As a result of its execution:

performs the division operation 10 / 100 and assigns the result to the variable x. In JavaScript, the division operation between two numbers results in a floating-point number.

The console.log(typeof(x)) statement outputs the type of the variable x to the console. Since the result of the division is a floating-point number, the typeof operator will return "number". Therefore, executing the code will display "number" in the console.

In the code snippet provided, there are two occurrences of the height variable. The outer scope declares and assigns the value 180 to height, and within the inner scope, a new block is created where another height variable is declared and assigned the value 200.

Inside the inner scope, the statement height = height + 10; increases the value of the inner height variable by 10, resulting in 210. However, this change is limited to the inner scope only and does not affect the outer scope’s height variable.

After the inner block finishes executing, the program continues to the console.log(height); statement in the outer scope. Here, the outer height variable with the value 180 is accessed and displayed in the console. Therefore, the output will be 180.

In the code snippet provided, there are multiple declarations of the counter variable. JavaScript does not allow redeclaration of variables using the let keyword within the same scope. Therefore, attempting to declare the counter variable more than once will result in an error.

When the code reaches the second line let counter = 200;, it will throw a “SyntaxError: Identifier ‘counter’ has already been declared” because the counter variable has already been declared in the previous line.

To fix this issue, you should only declare the counter variable once and then assign different values to it as needed, as shown in the following corrected code:

let counter = 100;
counter = 200;
counter = 300;
