Uncaught TypeError: THREE.Loader.load is not a function

This error occurs when trying to use the function `THREE.Loader.load()` but it is not defined or available in the current scope.

To resolve this issue, ensure that you have imported the necessary Three.js libraries and that they are properly loaded before attempting to use `THREE.Loader.load()`.

You can also check if there is a typo in the function name or that the version of the Three.js library you are using supports the `load()` function.

Here is an example of importing the necessary libraries for Three.js and using `THREE.Loader.load()`:

import * as THREE from 'three';
import {OBJLoader} from 'three/examples/jsm/loaders/OBJLoader.js';

const loader = new OBJLoader();
loader.load(
    'model.obj',
    function ( object ) {
        scene.add( object );
    },
    function ( xhr ) {
        console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );
    },
    function ( error ) {
        console.log( 'An error happened' );
    }
);

In this example, we are importing the `THREE` library and the `OBJLoader` from the `three/examples/jsm/loaders` directory. We then create a new instance of the `OBJLoader` and use the `load()` function to load a 3D model.
