Why JavaScript & TypeScript?
Efficiency

Java Script code can be processed using the resources on the user’s system and it allows us to build fast and efficient apps.

A big pool of developers

There are lots of Java Script & TypeScript developers who contribute to the development of JavaScript and TypeScript technologies, at Proffiz, in particular.

Good speed

Prepare for code and functions that run immediately without waiting for an answer from the server with TypeScript web development.

Substantial functionality

JavaScript and TypeScript can help to create a diversity of components and commands that improve the UX/UI of applications. As well, JavaScript can be migrated to TypeScript.

We are experts in
Node.js
Proffiz specialists are well-versed in Node.js development applying this technology on a number of projects. One of its core advantages is scalability: you can get web-based apps with excellent real-time responses.
Serverless
We use Serverless Framework as it helps to significantly decrease overhead and costs throughout the development, deployment and troubleshooting of serverless applications Proffiz builds for you.
React
Our JavaScript and TypeScript developers create real-time web applications using React.js. We use this library to ensure a seamless development process since with React.js we obtain such benefits as real-time updates, server-side rendering, maintainability and more.
Vue.js
By using Vue.js we face many benefits for successful application development. Vue.js doesn’t consume too much memory storage and possesses integration capabilities and flexibility that help us deliver creative solutions.
Angular
Angular lets software developers create functional and attractive web applications, empowering the development teams with faster development due to the robust Angular ecosystem and component-based architecture. With Angular, we can build high-performing apps for you.
React Native
Our software engineers use React Native since it allows us to create truly native applications and it doesn’t compromise the UX. As well as, with React Native we can iterate the development at a high speed.
Electron
Proffiz finds Electron a very essential technology because it helps us create strong native applications using JavaScript. Moreover, compatibility with macOS, Windows, and Linux makes Electron apps cross-platform.
