Assessment wanted for my Arrays skill test (Tasks 1 - 4)

MDN Learn
1

Hello, Please I would like an assessment of learning about Arrays on MDN. I have completed the Assessment Test Skills here, and below are the links to my code on CodePen:

Arrays: Task 1
Arrays: Task 2
Arrays: Task 3 (I have a question about this)
Arrays: Task 4 (Something seems not to be working here too).

As for Task 3, can you please check if I was able to get the code correctly for looping and printing the index number of an array? :slight_smile:

For Task 4, I use the right code which is startsWith() but am not sure why it is showing birds.startsWith() is not a function error :confused:

Thank you

Hello! startsWith() method is a string method, not an array. So try this code:

const eBirds = [];
  for (bird of birds){
    if (bird.startsWith('E')){
      eBirds.push(bird);
    }
  }

instead of yours:

eBirds = birds.startsWith('E',0);

Here I create new array eBirds. After that I check each birds array elements if it’s first letter is ‘E’. If true then I push this element into eBirds array.
I hope this helps you with task 4.

Thank you for sharing this.

It is quite helpful with the explanation.

I have made some changes now. Can you please recheck?

Hello! It would be better to declare the bird variable or const inside the for loop like this:

for (const bird of birds)

instead of

for (bird of birds)

I forgot to do it in my previous answer. Sorry about that.

Thank you for the reminder.

I just recall I ought to declare the variable as well :slight_smile:
I have made the changes now.

Can you please check Task 3: Assessment wanted for my Arrays skill test (Tasks 1 - 4) if I did it right
