      I'd say as a teacher he has the tendency of all talented ppl in their fields and has a little trouble relating to the noob, but comparing these lectures to the ones on the same topics in uni--pretty fascinating. Primeagen is a worse teacher but an overall much more interesting speaker. X factor.

      Isn't it a mistake? He's checking j vs j not j vs i. Lol

    • @alamba78
      @alamba78 6 місяців тому

      ⁠​⁠@@zwillx3953while his method of explaining is a bit confusing, it actually works because here he is using i to keep track of the sorted element and j and j+1 are doing the comparison and swap. So, when i = 0, you go into the inner loop of j and compare that first element with every subsequent element and keep bubbling the higher value to the end. Then i increments by 1 which takes the sorted element at the end of the array out of the comparison and swap being done in the inner j loop since that is already sorted from the previous iteration and again you go into the inner j loop and do the comparison and swap all the way through bubbling the higher value to the end. This continues till you satisfy the condition of the outer i loop. Hope it makes sense. Best thing is to write it down with a sample unsorted array of numbers and manually walk through the algorithm and writing the new array at each step. You will understand it better that way.

    It would be great if portions of each video were available even if it was 1-3 minutes of each. The reason I say this is because I usually use that as my "floober doober" test to see whether the video will be cohesive, I'll be able to follow it, or if it will be floober doober material. I expect Prima to have pristine content, but I also don't know if I'd be able to digest that content. Most sites offer a free trial but really what I'm looking to do is see how much of Frontend Masters would stick if I subscribed.

    It’s very useful for describing asymptotic behavior of functions generally, not just in programming.

      No because time complexity isn't about concrete implementation. You purely look at it in terms of pseudocode, and count the "steps".
      He's actually making it more confusing by using real code, so you asked a fair question.
      It's also worth noting that big O refers to the maximum growth. Eg "grows no faster than, or worst case". Theres also big omega: "grows no slower than, or best case" and big theta
      The whole thing is kinda explained poorly. It's really not much different to describing the growth rate of math functions. The O part just means "upper bound of"

    Don't JS object actually have a unique id? I mean, they don't have it explicitely defined but it's the reason why you can't compare the same objects.
    E.g.
    let a = { name: "" }
    let b = { name: "" }
    let c = a
    a == b is false but a == c is true because it looks at their references in memory.
