We don't allocate any initial capacity for this string, even though the approximate length of the string can be known ahead of time. This results in extra reallocations that aren't necessary. By computing the string capacity, we significantly reduce the number of reallocations. Not a super significant time or memory win, but this is one of the highest allocating lint rules. Running on `vscode`: Metric | Before | After | Reduction -- | -- | -- | -- Allocations | 4,071,066 | 4,071,066 | N/A Reallocations | 2,358,085 | 1,376,677 | 41.6% Allocated bytes | 882,448,204 | 815,245,566 | 7.6%

/oʊ ɛks siː/
The Oxidation Compiler is a collection of high-performance tools for JavaScript and TypeScript written in Rust.
Oxc is part of VoidZero's vision for a unified, high-performance toolchain for JavaScript. It powers Rolldown (Vite's bundler) and enables the next generation of ultra-fast development tools that work seamlessly together.
For more information, check out our website at oxc.rs.
* Oxidation is the chemical process that creates rust
🙋 Who's using Oxc?
Rolldown and Nuxt use Oxc for parsing. Rolldown also uses Oxc for transformation and minification. Nova, swc-node, and knip use oxc_resolver for module resolution. Preact, Shopify, ByteDance, and Shopee use oxlint for linting.
