Hello everyone, my name is Tong Oppa. Welcome to this issue of Front-end Canteen Technology Weekly, let's take a look at last week's technical information.

Technical Information

1. TypeScript 4.8

What's New since Beta and RC

Since the beta release, the stable version now supports the editor option to exclude specific files from automatic import. In addition, this release announcement also supplements the content not recorded in the release announcements of the Beta and RC versions (type inference in binding mode, syntax modification of decorators).

Major update

• Improve intersection types, union types and type narrowing;
• Improve type inference for infer in template string types;
• --build, --watch, and --incremental performance improvements;
• Improve error prompts when comparing object and array literals;
• Improve type inference for binding schemas;
• Fix file monitoring (especially git checkout scenarios);
• Find-All-Reference performance improvements;
• Exclude specific files from automatic import;
• Correctness fixes and breaking updates.

2. Deno 1.25

Major update

• Add deno init initialization subcommand;
• Experimental npm support;
• New HTTP Server API;
• Improve startup time;
• Improve FFI API.

Now let's look at the technical data.

Technical Information

1. Terminal Gif Maker

Terminal Terminal Gif generator, supports custom commands, fonts, display time, etc.

2. CSS :has() pseudo-class

The :has() pseudo-class specification was formulated very early, but because browser manufacturers were concerned about the impact of performance, it has not been supported, and this wait is 24 years. Until the Igalia company solved the performance problems that the browser could not solve for decades.

Safari 15.4 and Chrome 105 are currently supported, and Firefox has also opened experimental support.

3. A Collection of Data Structures and Algorithms Implemented in Rust

This repository summarizes and documents data structures and algorithms implemented in Rust.

4. Deno cheat sheet

The Deno memorandum classifies and marks the API status from three types of APIs: Deno runtime API, Web API and standard library. Click to go to the detailed documentation of the API.

5. Explain Shell

Details of the parameters are provided to help you understand the entire command.
