Develop smart contracts to specify terms and conditions, create and manage digital assets, enable peer-to-peer transactions, automate business processes, track movement in supply chain management, and more using JavaScript smart contract libraries. JavaScript is a programming language that is commonly used for building web applications. It is a high-level, interpreted language that is easy to read and write.
Smart contracts are self-executing contracts, with the terms of the agreement between buyer and seller being directly written into lines of code. The code and agreements exist across a distributed, decentralized blockchain network. JavaScript is a flexible and popular programming language used to create smart contracts. JavaScript is a popular choice for smart contracts because of its portability, versatility, and ease of use. JavaScript enables programmers to quickly create and publish smart contracts that can be used on numerous blockchain systems.
Any platform that supports JavaScript and permits the deployment of smart contracts is compatible with JavaScript smart contracts. This contains various well-known blockchain platforms such as TRON, EOS, and Ethereum.
