    Hi.
    Verge 4.3.0

    I am trying to load data from a .csv file and use it in different places in the application.

    Variables defined inside puzzle “load data” are local. Is there a special reason for this? How can I use the “Products” variable defined inside the puzzle “load data” outside the puzzle “load data”?

    In this case, the variable “Products” has a null value if it is outside the puzzle “load data”

    The first variant is correct, in the second variant you are trying to read the variable before it has been defined. this variable is not local, it’s just undefined yet. once ready do slots are not just for fun and beauty, they are used in functions which take some time to complete all actions.

    you can do it right after data have been loaded. for example, you can use a time delay to read this variable in 1-2-3 seconds

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

    OK, thanks.

    I actually thought that the next puzzle in the sequence is only triggered in the program if the previous puzzle is completed. just like a line in a program.

    In general it works as you described. But some function (async, Promise) require some time to be completed and they run in parallel threads while other functions continue running in the main thread one by one. Such as load scene, load data, append scene, replace texture etc.

    Puzzles and JS. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.
