Deep dives
Journey into Software Development
Gil Tayar shares his extensive journey into software development, which began at the age of 13 when he received a ZX81 computer. He transitioned through various technologies and programming languages, including Turbo Pascal and C, while gaining practical experience as an instructor in the army's School of Software Engineering. Over the years, he worked for notable companies like Wix and eventually joined Microsoft, contributing significantly to Node.js. His passion for mentoring newcomers in the tech field is evident, as he actively assists junior developers in navigating the challenges of entering the industry.
Embracing Change in Technology
Tayar emphasizes the importance of staying current with emerging technologies and trends in the software industry. He mentions the various revolutions he has witnessed, such as the shift from procedural to object-oriented programming and the rise of AI. His enthusiasm for exploring new frameworks, languages, and tools is evident, as he delights in discussing how solutions evolve to address existing problems. This adaptability is crucial for developers to effectively engage with the modern landscape, especially as younger generations enter the field with different skill sets and experiences.
The Challenges of Modularization
Tayar articulates his views on the significance of modularization in software development, expressing concerns regarding monorepos versus polyrepos. He argues that maintaining independence among packages is vital for manageable configurations and more straightforward debugging. By encouraging each package to have its configuration, Tayar believes developers can avoid complexities that arise when sharing configurations across multiple packages. His hands-on experience in managing extensive codebases underscores the importance of well-structured, independent modules that are easy to comprehend and maintain.
The Evolution of JavaScript Modules
Tayar discusses the evolution of module systems in JavaScript, contrasting CommonJS with ECMAScript Modules (ESM). He describes how ESM, introduced in ES6, brought a more standardized approach to modules that allows for improved compatibility and clarity. Despite the challenges of transitioning from CommonJS to ESM, Tayar points out the benefits of adopting ESM for building scalable applications. He believes that with more packages moving towards ESM, the Node.js ecosystem will ultimately become more robust and efficient in handling modularization.
Gil Tayar is a Principal Software Engineer at Microsoft, developer advocate, and conference speaker. Gil’s contributions to the Node.js ecosystem include adding support for ECMAScript Modules in Node.js to Mocha and TestDouble. He joins the show to talk about his history in software engineering, monorepos vs polyrepos, the state of JavaScript, and more.
Josh Goldberg is an independent full time open source developer in the TypeScript ecosystem. He works on projects that help developers write better TypeScript more easily, most notably on typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. Josh regularly contributes to open source projects in the ecosystem such as ESLint and TypeScript. Josh is a Microsoft MVP for developer technologies and the author of the acclaimed Learning TypeScript (O’Reilly), a cherished resource for any developer seeking to learn TypeScript without any prior experience outside of JavaScript. Josh regularly presents talks and workshops at bootcamps, conferences, and meetups to share knowledge on TypeScript, static analysis, open source, and general frontend and web development.
