Equivalent code in JS

Create a new cli wallet
```
solana-keygen new
```

Set the RPC url

solana config set --url https://api.devnet.solana.com

Create an empty JS file
```
 npm init -y
 touch index.js
```

Install dependencies

npm install @solana/web3.js @solana/spl-token

Write a function to airdrop yourself some solana

const {Connection, LAMPORTS_PER_SOL, clusterApiUrl, PublicKey} = require('@solana/web3.js');

const connection = new Connection(clusterApiUrl('devnet'));

async function airdrop(publicKey, amount) {
    const airdropSignature = await connection.requestAirdrop(new PublicKey(publicKey), amount);
    await connection.confirmTransaction({signature: airdropSignature})
}

airdrop("GokppTzVZi2LT1MSTWoEprM4YLDPy7wQ478Rm3r77yEw", LAMPORTS_PER_SOL).then(signature => {
    console.log('Airdrop signature:', signature);
});

Check your balance
```
solana balance
```

Create token mint

const { createMint } = require('@solana/spl-token');
const { Keypair, Connection, clusterApiUrl,  TOKEN_PROGRAM_ID } = require('@solana/web3.js');

const payer = Keypair.fromSecretKey(Uint8Array.from([102,144,169,42,220,87,99,85,100,128,197,17,41,234,250,84,87,98,161,74,15,249,83,6,120,159,135,22,46,164,204,141,234,217,146,214,61,187,254,97,124,111,61,29,54,110,245,186,11,253,11,127,213,20,73,8,25,201,22,107,4,75,26,120]));

const mintAthority = payer;

const connection = new Connection(clusterApiUrl('devnet'));

async function createMintForToken(payer, mintAuthority) {
    const mint = await createMint(
        connection,
        payer,
        mintAuthority,
        null,
        6,
        TOKEN_PROGRAM_ID
    );
    console.log('Mint created at', mint.toBase58());
    return mint;
}

async function main() {
    const mint = await createMintForToken(payer, mintAthority.publicKey);
}

main();

Verify token mint on chain
- Check the token on solana fm https://solana.fm/address/ChNkv9iW5pZJ1YAsNswC2CrdMUkFJBUbRWinjdLvKpXA/transactions?cluster=devnet-solana
- Use the getAccountInfo to see the data and lamports in the account

Create an associated token account, mint some tokens

const { createMint, getOrCreateAssociatedTokenAccount, mintTo } = require('@solana/spl-token');
const { Keypair, Connection, clusterApiUrl,  TOKEN_PROGRAM_ID, PublicKey } = require('@solana/web3.js');

const payer = Keypair.fromSecretKey(Uint8Array.from([102,144,169,42,220,87,99,85,100,128,197,17,41,234,250,84,87,98,161,74,15,249,83,6,120,159,135,22,46,164,204,141,234,217,146,214,61,187,254,97,124,111,61,29,54,110,245,186,11,253,11,127,213,20,73,8,25,201,22,107,4,75,26,120]));

const mintAthority = payer;

const connection = new Connection(clusterApiUrl('devnet'));

async function createMintForToken(payer, mintAuthority) {

        connection,
        payer,
        mintAuthority,
        null,
        6,
        TOKEN_PROGRAM_ID
    );
    console.log('Mint created at', mint.toBase58());
    return mint;
}

async function mintNewTokens(mint, to, amount) {

        new PublicKey(to)
      );

      console.log('Token account created at', tokenAccount.address.toBase58());
      await mintTo(

        tokenAccount.address,
        payer,
        amount
      )
