How do I increase electron forge memory heap size?

I have a template app made with electron forge, and when I try to execute the following code

const ARRAY_LENGTH = 1.1e8;
const randomArray = [];
for (let i = 0; i < ARRAY_LENGTH; i += 1) {
  randomArray.push(Math.random());
}

I believe I run out of memory with the following error:

<--- Last few GCs --->

[23850:0x7900000000]    16762 ms: Mark-sweep (reduce) 3622.1 (3706.7) -> 3478.0 (3562.6) MB, 1806.7 / 0.0 ms  (+ 0.5 ms in 1 steps since start of marking, biggest step 0.5 ms, walltime since start of marking 2717 ms) (average mu = 0.589, current mu = 0.60[23850:0x7900000000]    20404 ms: Mark-sweep (reduce) 3478.0 (3562.6) -> 3286.0 (3370.6) MB, 3640.7 / 0.0 ms  (average mu = 0.307, current mu = 0.000) last resort GC in old space requested


<--- JS stacktrace --->

I'm wondering how I increase the memory available to the process?

Note: tried adding preload script in forge.config.js as described here, using the following (to no avail, although the preload script does run):

// preload.ts
import { remote } from 'electron';

remote.app.commandLine.appendSwitch('js-flags', '--max-old-space-size=8192');

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...
