The NEAR Protocol: A New Frontier for JavaScript Developers

The introduction of JavaScript SDKs represents a significant paradigm shift in the blockchain space.For a long time, blockchain development was often perceived as a domain reserved for specialized developers proficient in languages like Solidity or Rust. 20 million JavaScript devs can now build applications on NEAR: KBW 2025 applications Build devs JavaScript KBW million CryptonewsNEAR's decision to embrace JavaScript levels the playing field, inviting a massive influx of talent and diverse perspectives.

Why JavaScript?

JavaScript is arguably the most popular and widely used programming language in the world.Its accessibility and versatility make it an ideal choice for developers of all skill levels. KBW2025 quot;20 million JavaScript devs can now build applications on Near - A student can build an app without needing to learn new languages withoutHere's why leveraging JavaScript for blockchain development is a game-changer:

Large Developer Pool: With an estimated 20 million JavaScript developers worldwide, the potential talent pool is enormous.
Ease of Learning: JavaScript is relatively easy to learn compared to more complex languages like Rust or Solidity.
Versatility: JavaScript is used in front-end, back-end, and mobile development, making it a highly versatile language.
Existing Ecosystem: A vast ecosystem of libraries, frameworks, and tools already exists for JavaScript, further simplifying development.

Unlocking the Potential of Smart Contracts with JavaScript

The core of blockchain technology lies in smart contracts, self-executing agreements written in code.Traditionally, creating smart contracts required learning a specific language like Solidity for Ethereum or Rust for Solana and NEAR (before this update). Hot News. Hot News. 副标题Now, with JavaScript SDKs, developers can write smart contracts on NEAR using their existing JavaScript knowledge.

How it Works: JavaScript SDKs for NEAR

The JavaScript SDKs provide the necessary tools and libraries to interact with the NEAR blockchain.These SDKs enable developers to:

Write and deploy smart contracts: Create secure and efficient smart contracts using JavaScript.
Interact with existing smart contracts: Call functions and access data from deployed smart contracts.
Build decentralized applications (dApps): Develop user-friendly dApps that leverage the power of the NEAR blockchain.
Manage accounts and keys: Securely manage user accounts and cryptographic keys.

Essentially, the JS SDK acts as a bridge, translating JavaScript code into instructions that the NEAR blockchain can understand and execute.

Benefits of Building on NEAR with JavaScript

Choosing the right blockchain platform is crucial for the success of any dApp project.NEAR offers several advantages that make it an attractive option for JavaScript developers:

Speed and Scalability

NEAR utilizes a sharding technology called Nightshade to achieve high transaction throughput and low latency. A student can build an app without needing to learn new languages without needing to learn new skills, said NEAR founder Illia Polosukhin. 20 million JavaScript developers will now have the ability to write blockchain smart contracts and build applications on the NEAR Protocol, after rolling out JavaScript Software Development Kits (JS SDKs) on Monday.This ensures that dApps built on NEAR can handle a large number of users without performance degradation.

User-Friendly Onboarding

NEAR offers a user-friendly onboarding experience that makes it easy for new users to interact with dApps.This includes features like:

Human-readable account names: Instead of complex hexadecimal addresses, users can create accounts with easy-to-remember names.
Gas fee delegation: Developers can cover the gas fees for their users, eliminating a major barrier to adoption.

Sustainability

NEAR is committed to sustainability and aims to be climate neutral.The protocol uses a Proof-of-Stake (PoS) consensus mechanism, which is more energy-efficient than Proof-of-Work (PoW) used by Bitcoin.

Developer-Friendly Ecosystem

NEAR provides a rich ecosystem of tools and resources to support developers, including:

Comprehensive documentation: Detailed documentation and tutorials to help developers get started.
Active community: A vibrant and supportive community of developers who are willing to help each other.
Grants and funding opportunities: NEAR offers grants and funding opportunities to support promising dApp projects.

KBW 2022: The Launchpad for JavaScript on NEAR

Korea Blockchain Week (KBW) 2022 served as the perfect platform to announce the release of the JavaScript SDKs. 20 million JavaScript builders will now have the power to write down blockchain good contracts and construct functions on the Close to Protocol after rolling.This event brought together leading experts, developers, and investors from around the world, creating a buzz around NEAR's latest innovation.

Illia Polosukhin's Vision

Getting Started with JavaScript on NEAR: A Practical Guide

Ready to dive into building dApps on NEAR using JavaScript? 20 million JavaScript developers will now have the ability to write blockchain smart contracts and build applications on the NEAR Protocol, after rolling out JavaScript Software Development Kits (JS SDKs) on Monday.Here's a step-by-step guide to get you started:

Step 1: Setting Up Your Development Environment

Before you can start writing code, you need to set up your development environment. 20M JavaScript devs are now able to build applications on NEAR: KBW 2025 . news and more. Buy, Sell and Swap bitcoin, ethereum and 350 cryptocurrencies on BitSwapNowThis involves installing the necessary tools and libraries.

Install Node.js and npm: Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a web browser. npm (Node Package Manager) is used to install and manage JavaScript packages.You can download Node.js from the official website: https://nodejs.org/
Install the NEAR CLI: The NEAR Command Line Interface (CLI) is a tool that allows you to interact with the NEAR blockchain from your terminal.You can install it using npm:
```
npm install -g near-cli
```
Create a NEAR wallet: You'll need a NEAR wallet to deploy and interact with smart contracts. Great to see that the NEAR Protocol is now supporting Javascript as a language to write smart contracts. We need more of these to make blockchain coding easier and more accessible blockchain coding crypto web3You can create a wallet using the NEAR CLI:
```
near login
```

Step 2: Installing the JavaScript SDKs

Now that you have your development environment set up, you need to install the NEAR JavaScript SDKs. A student can build an app without needing to learn new languages without needing to learn new skills, . Markets One News Page: TuesdayYou can do this using npm:

npm install near-api-js

Step 3: Writing Your First Smart Contract

Let's write a simple smart contract that stores and retrieves a greeting message.

Create a new file called `greeting.js`:


// greeting.js
import { NearBindgen, near, call, view } from 'near-sdk-js';

@NearBindgen
class Greeting {
  constructor() {
    this.message = ""Hello, NEAR!"";
  }

  @view
  get_greeting() {
    return this.message;
  }

  @call
  set_greeting({ message }) {
    near.log(`Setting message to ${message}`);
    this.message = message;
  }
}

Compile the smart contract: You'll need to use a tool like `browserify` to bundle the JavaScript code into a format that can be deployed to NEAR.First install `browserify`:
```
npm install -g browserify
```
Then bundle your code:
```
browserify greeting.js -o greeting.bundle.js
```
Deploy the smart contract: Use the NEAR CLI to deploy the compiled smart contract to your NEAR account:
```
near deploy --wasmFile greeting.bundle.js --accountId your_account_id
```
(Replace `your_account_id` with your actual NEAR account ID).

Step 4: Interacting with Your Smart Contract

Now that your smart contract is deployed, you can interact with it using the NEAR CLI or the JavaScript SDKs.

Get the greeting message:
```
near view your_account_id get_greeting
```

Set a new greeting message:

near call your_account_id set_greeting '{""message"": ""Hello, World!""}' --accountId your_account_id

This is a basic example, but it demonstrates the core concepts of writing and deploying smart contracts on NEAR using JavaScript.The NEAR documentation provides more comprehensive examples and tutorials to help you build more complex dApps.
