javascript checking if value exists in array, then using from array in function

The javascript i am dealing with assigns random array names, made out of 2 letters**, letters only,both caps and sml.. i am looking for a specific address in one or more of those arrays, let it be 100, so the array looks like this :

AF[0:0, 1:0, 2:0, 3:1, 4:1, 5:0, 6:0, 7:15, 8:15, 9:15, 10:15 ......100:10,150:50,500:3]

and some extend pass my 100 mark, those are the ones i am after : so what i did was : get a list of all 2 digit, letters only (Aa,Bb,Cg,...) arrays that a page already has, named it doubleDigits making up an array of all possible hits on a name with 2 digits : came out to 1326 possible hits named it results compare both arrays, came up with a smaller number of possibilities, around 200 or so. named it intersection: now my file looks like this : intersection (249)  (the following is a console.log of intersection, it does not show the keys, the keys are starting with zero up to 249 ...or wherever the file stops.) ["AB", "AD", "AF", "AI", "AQ", "AR", "AU", "Aa", "Ab", "Aj", "Ao", "At", "Ax", "BE", "BG", "BH", "BJ", "BN", "BP", "BQ", "BR", "BV", "BY", "BZ", "Ba", "Bc", "Bg", "Bk", "Bl", "Br", "Bu", "Bw", "By", "CD", "CI", "CM", "CN", "CT", "CV", "CZ", "Cd", "Cf", "Cj", "Cl", "Cv", "Cw", "DF", "DI", "DP", "DQ", "Dd", "Dn", "Dp", "Dv", "EG", "EN", "EQ", "EV", "EW", "Eb", "Ec", "Ee", "Ei", "Ej", "Em", "En", "Ep", "Es", "Et", "Ey", "Ez", "FJ", "FR", "FV", "FZ", "Fa", "Fd", "Fh", "Fj", "Fk", "Fm", "Fn", "Fq", "Fs", "Fu", "Fw", "GP", "GQ", "GS", "GT", "GV", "GY", "Gc", "Ge", "Gf", "Gk", "Gn", "Gq", "Gy", "HO", …]

i need to check each value, against my target, which is done on console by typing AB[100] and will tell me if there is a value there or not., then taking these valid values from all to a new array. i am using scripts from this site to do the work, but i have no idea where to go from here.

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
