[@kevinvikan8115]

Great video, learning by practicing is so much better. Even if all you do is copying a few lines of code that you see in each lesson. Much more effective than just taking notes. I know this because I tried everything and the only way I could learn (and retain what I learned) was when I started doing that. Once a friend suggested me a few books with interactive content, that made me practice what I learned at each chapter. Edit: For those asking about the books I mentioned, these are the best ones: "Javascript In Less than 50 Pages" "Head First Javascript Programming" If you are into learning Python, "Smarter Way to Learn Python".

[@itsnobledean9450]

I completed this video 4 whole weeks ago! Wow! I just came back today to rebuild it, with functional programming concepts, and man, I know my life has revolved around JavaScript for the last 4 weeks, but coming back to videos like these have really helped me understand how to properly use conditionals, and most of all, how to organize my builds with a functional programming mind frame. I separate the date from the functions, and I use map and join for the reels. I broke it up into a bunch of smaller functions with specific tasks.

[@dominikbogdanski9244]

Great video! Also, when asking for amount of lines to bet on we can do this: const lines = prompt("Enter amount of lines to bet on (1-" + ROWS + "): "); so it changes as we change number of rows in our slot machine

[@Snsnnsnn-b7h]

I think a lot of people are missing out from the real intention of this video. He is simply going though all the vanilla JavaScript topics any newbie or beginner should be familiar with in thier early stages of JavaScript development . Topics such as declaring and assigning variables, for loop or while loop, JavaScript functions arrow functions, debugging etc He is simply trying to do what should normally take months to learn and master and try to make it as simple and perhaps encourage learning the fundamentals I found the video extremely helpful and insightful, in so my opinion so many ways to kill a bird and surely this is one way to it Well done Tim

[@punksterbass]

thank you Tim, this was my first introduction to Javascript (coming from a Python background) and it was immensely helpful

[@moebidaz]

This project was truly helpful! I just have a small suggestion regarding the code at 19:16. Instead of using (.numberOfLines > 3), it would be better to use (.numberOfLines > ROWS). Just to ensures that the code remains intact even when we alter the value of ROWS.

[@Sahil-ev5pm]

Hey buddy can u explain why tim didn;t get error even though he re declared blocked variable const numberoflines

[@yessirski7868]

@@Sahil-ev5pm if I am not mistaken, it's because the first number of lines was inside of a function, meaning it isn't global. unless it is a constant outside of the function, you are free to use it again.

[@finnikey]

Something to note at 20:30 - the order matter for const functions. If you use the function keyword, they are 'hoisted' to the top and can be placed in any order. For example, the following would work because it is using the function keyword: const numLines = promptNumLines(); function promptNumLines() { const minLines = 1; const maxLines = 3; while (true) { const lineAmount = prompt("Enter a line amount (" + minLines + "-" + maxLines + "): "); const numLineAmount = parseFloat(lineAmount); if (isNaN(numLineAmount) || numLineAmount < minLines || numLineAmount > maxLines) { console.log("Invalid line amount. Please try again."); promptNumLines(); } else return numLineAmount; } }

[@ujjwalgupta6503]

To whoever had trouble understanding the random number selector, here's a comprehensive explanation: Math.random() will give us a number between 0 to 1 here 0 is inclusive and 1 is exclusive what this means is the number could be 0, 0.1, 0.2, 0.3, ......, 0.99999 maxx so multiplying it by the length let's say it's 10 would give us a range from 0 to 9.9999 inclusive now the number could be 3.6 etc but the index is only a whole number so the Math.floor() function will effectively remove the decimal part or can be interpreted as shifting the number to the lowest whole number: 9.9 -> 9 3.3 -> 3 4 -> 4 0 -> 0 0.1 -> 0 0.999 -> 0 since indices start from 0 an array with 10 elements would have range 0 -> 9 and the random number expression would also have range 0 -> 9
