Can we use dynamodb without nodejs ?

Hello guys, how are you I am a beginner in AWS and I wanna know can I use plain JavaScript to store values and manipulate them using DynamoDB.

const { DynamoDBClient } = require('@aws-sdk/client-dynamodb');
const { DynamoDBDocument } = require('@aws-sdk/lib-dynamodb');
// Create service client module using ES6 syntax.
//import { DynamoDBClient } from "@aws-sdk/client-dynamodb";
// Set the AWS Region.
const REGION = "ap-south-1"; //e.g. "us-east-1"
// Create an Amazon DynamoDB service client object.
const ddbClient = new DynamoDBClient({ region: REGION });


// Import required AWS SDK clients and commands for Node.js
import { CreateTableCommand } from "@aws-sdk/client-dynamodb";


// Set the parameters
const params3 = {
    AttributeDefinitions: [
      {
        AttributeName: "Season", //ATTRIBUTE_NAME_1
        AttributeType: "N", //ATTRIBUTE_TYPE
      },
      {
        AttributeName: "Episode", //ATTRIBUTE_NAME_2
        AttributeType: "N", //ATTRIBUTE_TYPE
      },
    ],
    KeySchema: [
      {
        AttributeName: "Season", //ATTRIBUTE_NAME_1
        KeyType: "HASH",
      },
      {
        AttributeName: "Episode", //ATTRIBUTE_NAME_2
        KeyType: "RANGE",
      },
    ],
    ProvisionedThroughput: {
      ReadCapacityUnits: 1,
      WriteCapacityUnits: 1,
    },
    TableName: "TEST_TABLE", //TABLE_NAME
    StreamSpecification: {
      StreamEnabled: false,
    },
  };
  
const run = async () => {
    try {
      const data = await ddbClient.send(new CreateTableCommand(params3));
      console.log("Table Created", data);
      return data;
    } catch (err) {
      console.log("Error", err);
    }
  };
  run();
