Divide and Conquer? - Exploring the 'JS0' and 'JSSugar' Proposal for JavaScript Evolution

Sasha Grief discusses the state of the web through web development surveys, leading to an interactive quiz about the state of JS and usage of front end frameworks. Discussion on popular front-end libraries like React, Vue, Angular, and the rising popularity of TypeScript among developers in recent surveys. Discussion on TypeScript adoption, TC39 committee proposals, favorite CSS feature 'has,' and browser support for 'has' selector. Browser interoperability, browser vendors' initiatives, AI usage among web developers, and survey insights. Job titles linked to higher income, diversity of survey topics, top hobby among developers, and popular specific video games. Learnings on CSS features, TypeScript default, AI usage, survey benefits, challenges in reaching diverse survey participants. Surprising positivity in JavaScript usage, stable framework landscape, AI adoption challenges, mainstream AI tools, successful situp.js survey. Inconsistent respondent numbers, manual data normalization efforts, subjective question selection process, community input, mitigation of selection bias. Reason for starting surveys, transition from Meteor JS, exploration of JavaScript ecosystem.

Remix is a web development framework that combines the scalability of server-rendered frameworks with the flexibility of React. It prioritizes web standards and best practices for security. Remix streamlines development with web standards like URLs, fetch API, HTML, and HTTP caching. It simplifies data handling through HTML forms and HTTP, improving user experience. Httpication in Remix reduces server load and speeds up response time, while global search and Storyblock make building complex websites easier.

The TC59 Type Annotations proposal, also known as Types with Comments, introduces the ability to run typed code in JavaScript. It aims to bring TypeScript back into JavaScript and create a separation between type system and runtime. TypeScript's popularity is on par with JavaScript, raising concerns about the influence of Microsoft. The proposal progresses by addressing runtime interaction and token soup in type specifications. Research, community involvement, and quantifying the effects of supporting this comment style are important goals.

Let's talk about web push notifications and their benefits. Web push notifications have higher opt-in and click rates compared to traditional methods. The web push API should be used responsibly, with subscription requests initiated only after explicit user action. Improve engagement by using emojis in notifications. Connect with the speaker on LinkedIn for more information about the web push API.

Today's Talk explores various Web APIs and their functionalities, including the Intersection Observer API for element visibility, the Network API for connection detection, and the Background Sync API for offline capabilities. The Broadcast Channel API enables communication between components and the Beacon, Web Speech, Web Share, Screen Awake Lock, Page Visibility, Background Fetch, and Web Authentication APIs offer additional functionalities. These standardized APIs work across browsers and can improve performance while reducing electricity consumption.

I'll speak today about the Temporal proposal, which adds modern date and time handling to JavaScript. Temporal is an API that'll be available in browsers soon and will add a built-in library for dates and times, avoiding the need for external libraries like Moment. It offers strong typing with different types for different data, such as calendar dates with or without time. Temporal objects are immutable and designed to work with JavaScript's internationalization facilities. It addresses deficiencies in the global Date object and introduces types like instant and plain types for accurate representation of time and dates across time zones. With the old Date, representing a date without a time can be problematic, especially in time zones where midnight is skipped due to daylight saving time. Temporal introduces types like PlainDate, PlainTime, PlainYearMonth, PlainMonthDay, and ZonedDateTime to accurately represent different scenarios. Additionally, there is a type called Duration for arithmetic operations and unit conversion. Now that I've introduced you to the cast of characters in Temporal, it's time to show how to accomplish a programming task. We'll start with an easy task: getting the current time as a timestamp in milliseconds using the instant type. To convert between Temporal types, you can either drop or add information. The toZonedDateTime method is used for conversion and requires adding a time zone and a time. Although Temporal objects are immutable, you can create new objects with replaced components using the with method. Migrating from the old Date object to Temporal offers a more reliable solution and avoids potential bugs. Check out the documentation for more details and enjoy using Temporal in your codebase!
