Incomplete details about how to complete challenge : Create String using Template literal

[mpmaan]

Describe your problem and - if possible - how to reproduce it

It is not mentioned that we should use map() function to solve it. The test Template strings were used fails if we use a for-loop to solve this challenge. I could pass it by using only map() function.

This code works

   const resultDisplayArray = arr.map((item) => `<li class="text-warning">${item}</li>`);

This doesn't work

    const resultDisplayArray = [];
    for(let i = 0; i < arr.length; i++){
        resultDisplayArray.push(`<li class="text-warning">${arr[i]}</li>`);
    }

Most probably the regex test fails because of the [ and ] characters while using for-loop.

Also, the $ characters are not rendered properly in the given example in the guide.
The example should have ${person.name} and ${person.age}.

Hmmm, the code appears to be correct in seed, but is not formatted correctly in the webpage.

@Nirajn2311 Also check this challenge , it has kind of simlar problem (see $ in second example).

I’ll see what I can do about the typos.
For everyone, I would appreciate if you told me all typos anyone finds as I am fixing it at curriculum repo(freeCodeCamp/curriculum#23).

@Bouncey The issue with $ sign may have been fixed but what about the map() function ?

@mpmaan, thank you for pointing out the issue with the formatting caused by MathJax. That was my fault for not checking how it affected all the challenge descriptions outside of the Interview Prep sections.

You're right that there is still an issue with this challenge due to the regex in the test being to specific. You can follow the discussion here: #16358

I plan on submitting a fix from one of my comments in that issue.

@scissorsneedfoodtoo thanks, i am sorry for creating duplicate issue.

@mpmaan, no worries! Better a duplicate issue than one going completely unreported. Good looking out!
