How to get the id of a block at set coordinates?

[past turtle]

In my current script I'm trying to detect the type.id of the block located at the newLocation variable coordinates. How would I go about checking? I know using detectable.includes() is required, but what do I need to add to the parameters of it to detect the block at the newLocation coordinates?

Here's my script so far:

``import { world, system, Block } from "@minecraft/server";

world.afterEvents.entityHitBlock.subscribe(e => {

const player = e.damagingEntity;
const block = e.hitBlock;
const bFace = e.blockFace;

const bLocation = block.location;
const startX = bLocation.x;
const startY = bLocation.y;
const startZ = bLocation.z;

const detectable = [
    "minecraft:diamond_ore"
];

function checkBlocks() {

    if (detectable.includes(block.type.id)) {

        console.log(`${block.type.id} detected`);
        return;
    }

    for (let i = 1; i <= 20; i++) {

        let newLocation;
        switch (bFace) {

            case "North":

                newLocation = { x: startX, y: startY, z: startZ - i };
                break;

            case "East":

                newLocation = { x: startX - i, y: startY, z: startZ };
                break;

            case "South":

                newLocation = { x: startX, y: startY, z: startZ + i };
                break;

            case "West":

                newLocation = { x: startX + i, y: startY, z: startZ };
                break;

            case "Up":

                newLocation = { x: startX, y: startY - i, z: startZ };
                break;

            case "Down":

                newLocation = { x: startX, y: startY + i, z: startZ };
                break;

            default: break;
        }
    }
}
