Check if class instance is instance of provided type

I have a function that dynamically loads a folder with ts files, initiates the classes in them and saves them. The function takes in a type for its return type like this load<T extends BaseInteraction>. But when i use DynamicClass instanceof T it says 'T' only refers to a type, but is being used as a value here.. is there a way to compare the class to the provided class?

Better way of finding element from map

Im making an api and all routes are stored in a map. is there a better and more optimised way to look if the route exists and to get it?

handleRequest(req: Request, info: Deno.ServeHandlerInfo): Response {
    const path = new URL(req.url).pathname;
    const route = this.getRoute(path);
    if (!route) return new Response("not found", {status: 404});
    console.log(route);

    return new Response("Hello World!");
}

getRoute(pathname: string): Route | undefined {
    const paths = pathname.split("/").filter(val => val.length > 0);
    const path = paths.join("/");
    let routes = Array.from(this.routes.keys());
    for (const route of routes) {
        const regex = new RegExp(`^(${route.replaceAll(/\[.*\]/g, "(.*)")})$`)
        if (!regex.test(path)) continue;
        return this.routes.get(route);
    }
        
}

handleRequest(req: Request, info: Deno.ServeHandlerInfo): Response {
    const path = new URL(req.url).pathname;
    const route = this.getRoute(path);
    if (!route) return new Response("not found", {status: 404});
    console.log(route);

Log Deno.command process output

i need to execute a command wich will keep running until stopped and log the output. i found this but it dosnt work

const command = new Deno.Command(
  "java",
  {
    args: [
      "-Xms512M",
      "-Xmx512M",
      "-XX:+UseG1GC",
      "-XX:G1HeapRegionSize=4M",
      "-XX:+UnlockExperimentalVMOptions",
      "-XX:+ParallelRefProcEnabled",
      "-XX:+AlwaysPreTouch",
      "-jar",
      "proxy.jar"
    ],
    stdout: "piped",
    stdin: "piped",
    stderr: "piped",
  },
);
const process = command.spawn();
for await (const line of readLines(process.stdout)) {
    emit_console_out(line);
}

const command = new Deno.Command(
  "java",
  {
    args: [
      "-Xms512M",
      "-Xmx512M",
      "-XX:+UseG1GC",
      "-XX:G1HeapRegionSize=4M",
      "-XX:+UnlockExperimentalVMOptions",
      "-XX:+ParallelRefProcEnabled",
      "-XX:+AlwaysPreTouch",
      "-jar",
      "proxy.jar"
    ],
    stdout: "piped",
    stdin: "piped",
    stderr: "piped",
  },
);
const process = command.spawn();
for await (const line of readLines(process.stdout)) {
    emit_console_out(line);
}

this says:

Argument of type 'ReadableStream<Uint8Array>' is not assignable to parameter of type 'Reader'. Property 'read' is missing in type 'ReadableStream<Uint8Array>' but required in type 'Reader'

and i know that process.stdout has a getReader but that dosnt seem to work either
