Javascript – The Most Popular Language in The Ethereum World


Javascript has been the most popular programming language on the web since it was introduced in 1995, and its popularity has only increased with time. The simplicity and flexibility of Javascript make it easy for anyone with basic computer skills to write code, and at the same time, it allows developers to create websites with as much power as their imaginations. Due to these features, Javascript has become one of the most popular languages across all of the Internet, but it’s especially important in the Ethereum world because of how many use cases the language has within blockchain development. How does Ethereum fit into this? Well, Ethereum uses something called Solidity, which is based on Javascript itself!

Ethereum, the second most popular cryptocurrency, is largely built on JavaScript. Become familiar with JavaScript if you want to participate in this ecosystem. The same goes for if you’re interested in using an Ethereum-based DApp (a Decentralized Application). In order to use these apps, you’ll have to know how to code JavaScript. The purpose of this article is to learn how javascript is the most popular language in Ethereum and also to discuss javascript jobs in Ethereum.

A Basic Understanding of Ethereum

Blockchain technology underpins Ethereum, a platform for open software development. Decentralized applications can be developed and deployed using it. Voting, domain names, financial exchanges, crowdfunding campaigns, and even legal contracts can all be codified, decentralized, secure, and traded on Ethereum.

Decentralized Finance

Financing new markets and projects with decentralized finance is a new idea. Conceptually, it doesn’t necessarily have to belong to a particular place or time. It could be that there are thousands, even millions of people from different cultures, languages, and countries around the world who wish to finance their own community endeavors. This would require some form of payment or transfer.

Smart Contract

Smart contract platforms like Ethereum allow the emergence of a new form of finance where all participants are brought together under a common financial contract. This can include people and companies, as well as projects around the world. The token sale made $18,000,000 in 3 days; this was the first time in history that a cryptocurrency raised capital through an initial coin offering (ICO).

How Does JavaScript Contribute to Ethereum’s Ecosystem?

The Ethereum world is dominated by JavaScript. It was originally conceived by Brendan Eich, who went on to be the CEO of Mozilla Corporation and CTO of Brave Software Inc. JavaScript has gone through many revisions since its inception. ECMAScript 2015 is the current version which includes modern features like arrow functions, classes, and modules. ECMAScript 2016 adds support for Decorators and Async Functions while ECMAScript 2017 adds asynchronous iteration via async functions.

In Ethereum’s ecosystem, JavaScript is used to access web3 objects and calls smart contract methods. It also helps with building decentralized applications (dapps) that use a single back-end codebase that can be accessed from a variety of clients including desktop browsers, mobile apps, or other Web applications.

There are many frameworks available for JavaScript, but there is one that has been gaining popularity lately and it’s called Truffle. It is used by many organizations such as Consensys and Microsoft Azure to build smart contracts and DApps. Truffle provides a suite of tools to make life easier for developers by simplifying development tasks like building, testing, deploying, and interacting with smart contracts.

JavaScript APIs For Ethereum

While Solidity is the most popular language for writing smart contracts, there are many JavaScript libraries that make it easy to interact with Ethereum. The web3.js library is a popular JavaScript library. An HTTP or IPC connection can be used to interact with Ethereum nodes using this library. You can use web3.js to send transactions, check account balances, and more. To work with web3.js, one needs to know how Ethereum works on a high level and have some experience programming with JavaScript since it is not as intuitive as other languages like Java or Python. However, web3.js makes things easier by providing wrappers around complex concepts like accounts, blocks, and transaction ids making it possible for developers who are new to the Ethereum world to still work with the blockchain easily.

Jobs Opportunity for JavaScript Developer in Ethereum

JavaScript jobs are in great demand. Some jobs are permanent positions, while others are freelance gigs. Freelance jobs may be project-based or hourly based, depending on the skillset you offer. Here are a few demanding jobs in Ethereum:

Solidity Developer

Solidity Developer is one of the most popular job titles in the Ethereum world. It’s a programming language that works on blockchain applications. It’s used to create contracts and other transactions, which can be deployed on various different types of blockchains like Bitcoin or Ethereum.

Full Stack Engineer

An engineer who understands both the front-end and back-end of a web application is known as a full-stack engineer. A full-stack engineer is comfortable working with HTML, CSS, JavaScript, and PHP. In Ethereum, engineers have to create smart contracts for every transaction and this process will be done by javascript. In other words, most developers are focusing their efforts on Javascript for development because it is the language that everyone knows how to use.

Blockchain Engineer

Blockchain Engineer is a position that deals with the coding of software to operate and secure blockchain networks. It is estimated that the median salary for this position is $110,000 USD per year, according to Glassdoor. Some popular languages used by blockchain engineers are Python, Java, C++, and JavaScript.


In conclusion, it is clear that the majority of all programmers are using JavaScript, which is a good sign for the future of Ethereum. It will be interesting to see how this language continues to grow and evolve, but it seems safe to say that it will be one of the most important languages for years to come.
