    Question Javascript example needed: func to sub and unsub to an item + func called on new data

    Hi,

    Im new to LS, so far it looks very exiting. Having completed the hallo world, I have the below very basic requests, as I prefer to put all in black-box functions with input and output:

    All using a 2 dimensional array. The array can be of fixed size, ie 100 rows with 4 columns.

    0) A function or code snippet which initiates LS;


    1) A function or code snippet which subscribes to a parameter ( a new row in the 2D array ), for example called with;
    function Subscribe( item_name, row,column);

    2) A function or code snippet which is called each time a value in the array has changed / a new value has been received, for example called with;
    function OnReceive( row,column);

    This is very much appreciated.
