After a while of learning JavaScript on FCC I eventually became stuck on basic algorithm scripting section.
I don't know how to reverse a string as I haven't done such before, though I know I'll probably use an array or there might be an inbuilt method for that, nor do I know how to return the biggest number from an array. My question now is;

I've learnt using books, videos and FCC + documentation from JavaScript dort info should I start learning how to approach algorithms or just read for the specific tests on FCC?

I'm at a level I could solve fizzbuzz, leap year challenges and simple things like converting fahrenheit to celsius though now I'm questioning my abilities because of these algorithms, plus taking a glance at the certification projects got my heart racing, those who've passed through the same experiences, what's your advice to approach the algorithms section on FCC and what skills should I learn along the way to make myself employable.

Note: I'm familiar with HTML, CSS(vanilla), SCSS, and bootstrap. Want to finish the JavaScript portion then move to react and redux and then node, express, bash and finally SQL in early 2024.

I'm thinking of approaching things by knowing what the inbuilt JavaScript prototypes do.
They're the ones you can see on your console by using console.log(Object.prototype) and console.log(Array.prototype) while also strengthening my understanding of loops.

Take it one step at a time. Learn how to solve problems instead.

You can't know all the inbuilt functions or prototypes like you mentioned.

Even if you know or learn them, you'll forget most/some. Some you won't be using through out your career life.

Learn how to break problems into steps (algorithm) and not bothering about the challenge on whatever platform.

Use Google. Even google developers use Google.

After breaking the steps down, then you can Google to learn the concepts you need (you'll come across thousands of articles on how to do that).

That way you can solve the challenge in whatever language.

For example I might choose to learn Go lang/Python and then use JavaScript FCC challenges to practice because I can break down the steps.

What exactly is your focus track? FE or BE? You really don't need to wait till "24 what happened to mid "23?

Choose a track FE or BE learn it well, build projects and apply for internships/jobs.

A string is an Array of characters, well except in Rust that treats Strings differently

Thank you for the thorough post, I'm learning to land a frontend role.

Great, let your learning be project driven.

There's a lot to learn. Whatever you learn make sure you're using it in a project or when you start a project there'll definitely be something to learn.

Good luck.

Hello bro!
I just started JS using sololearn app. I can deduce you are vast in programming languages.

What's the meaning of FE & BE sir?

Reversing a string should not be hard for you. Since you are familiar with array and you can loop through it, just start looping from the last element of the array.

Hint: last element is array.length-1

No please, I'm busy for now and mentorship requires a lot.

You can always your questions on here (I mean any thread) and mention me there a lot of E-mentors here willing to answer you.

There's an Array.reverse() method.

Hey bro. These things are not really hard to do, you just haven't got your basics yet. Read more on string and array and what they really mean. Read your loops and control flow very well and understand them. Try solving some programming challenges. Just keep at it , one day you will get it.
Also you don't need to know all inbuilt methods. You can just Google the ones you need. Or rather most string manipulation methods can be easily built from scratch with for loops. I will advise you to try building them when you need them.
Summary is that you have to get your basics down first.

They're good to know, but don't waste your time on them. Learn them when you're reading about Array, Objects or Classes.

You don't really need those prototype methods. With JavaScript ES6, you might not use those prototypes. So learn modern JavaScript (ES6 and above).

Spend time building actual projects instead. Your boss won't be interested in those inbuilt stuff. He/She just wants you to get things done.

So you'll mostly be working with libraries and frameworks (they're available to make us build faster. So use them).

Instead, learn how JavaScript works under the hood. The event loop and call stack.

I'll recommend a YouTube/Udemy course titled; "JavaScript: Understanding the weird parts."

Relax! Na small small. After u have learnt to reverse a string. Another one go still dey ahead... Calm down..

To reverse a string is very simple if you understand for let loops, while loops and co.

Instead of counting upwards,the normal way, count downwards to reverse a string. U will use the generated numbers to reference the array.

Instead of

for(let I = 0; I < string.length; I++){
console.log(string[I])
}

Do

for(let I = string. length-1; I >= 0; i--){
console.log(string[I])
}

U can manually do

String[5]
String[4]
String[3]
To
String[0]

To understand.

Feel free to drop any question, let me help u in my own small way.

Thank you so much bro, I am still learning JavaScript loops and have gotten the idea, the next stage now is how to access sub-arrays, 2D arrays.

Nice to hear.

2d/nested arrays are not hard... Just keep moving.. Goodluck.!

another way is trying using it solve something personal to you, even the basics. For example you talked about converting fareheight. You can try converting meters, kg and so on. You talked about leap year, you can try expanding to other time stuff. This more like generalizing to other examples. When you do it like that it becomes clearer and fun.
