TypeScript 宣布原生移植计划,性能将提升 10 倍

TypeScript 团队宣布将编译器及工具链移植至原生代码(Go 语言),目标在 2025 年实现里程碑式性能突破。新版本 tsc 编译器在主流项目测试中展现出 10 倍速度提升:VS Code 代码库类型检查耗时从 77.8 秒缩至 7.5 秒,编辑器项目加载时间更从 9.6 秒优化至 1.2 秒。该方案还将内存占用降低约 50%。

原生版本预计 2025 年中发布命令行检查工具,年底完成全功能支持。现有 JavaScript 代码库(TypeScript 6.x)将与原生版本(TypeScript 7.0,代号 "Corsa")并行维护,确保平稳过渡。升级后将支持实时全项目错误检测、高阶重构功能,并为 AI 开发工具提供新基建。

团队将于 3 月 13 日举办问答活动,开发者可通过 GitHub 仓库追踪进展并参与测试。此次性能跃迁被视为开发体验的革命性升级,或将重塑现代 TypeScript/JavaScript 开发范式。

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
