How to create arrays ( 4/5 mins ) - video 1

• Start with 10 different variables of the same type and then explain why this is a problem. What will happen when we create more and more of these variables?
• Emphasise zero-indexing in arrays
• Modifying arrays ( updating an item at a particular index )

for..of loop ( 5/10 mins ) - video 2

• You can check out the traditional for loop in the previous section
• Demonstrate use of for..of loop with an array

Walk through some code ( 10 mins) - video 3

• Step through a code example like a computer
• Show the debugger
• Pick an example of one function calling another ( days of the week from JS1 Week 3 syllabus notes )

Actions

• @alicagatay add some examples to the repo for your sections

Hi @moneyinthesky @SallyMcGrath , in the third exercise of financial-times mandatory homework JS-core1-week3, the explanation is :

The Financial Times wants to understand what the average number of characters in an article title is.
Implement the function below to return this number - rounded to the nearest integer.

function averageNumberOfCharacters(allArticleTitles) {
// TODO
}

allArticleTitles is an array of strings, the question is asking for getting the average number of characters in an article title which means the average number of characters in each string(sum of the whole characters in each string (title) and divided them by the whole characters in the article title array). we will have different average numbers for this array of title articles for each string inside of this array.
in the end, the question is saying that there is just one number to be returned.

I think there should be more clarification for this question like the lowest or highest average or which average of title we want them to return.

It looks like the tests are not working in the Action section of the repository. In previous weeks projects, they ran automatically on pull request.
