Bug报告

文件 node_modules/typescript/lib/lib.es5.d.ts ,行号 1386、1392、1393、1399。在 reduce(callbackfn: (previousValue: T, currentValue: T, currentIndex: number, array: T[]) => T) 方法中的 previousValue 参数在 JSDoc 中命名为 accumulator ,而不是 previousValue ,这可能会导致在阅读提供的文档时产生混淆。

🔎 搜索词

Array<T>.reduce<U> , Array<T>.reduce<U>(callbackfn:(previousValue , accumulator

// Welcome to the TypeScript Playground, this is a website
// which gives you a chance to write, share and learn TypeScript.
// You could think of it in three ways:
//
//  - A location to learn TypeScript where nothing can break
//  - A place to experiment with TypeScript syntax, and share the URLs with others
//  - A sandbox to experiment with different compiler features of TypeScript
const anExampleVariable = "Hello World"
console.log(anExampleVariable)
const arr = ['foo', 'bar', 'baz', 'acc'];
const reduceArr = arr.reduce((prev, curr) => {return prev.concat(curr);});

🙁 实际行为

previousValue 参数在 JSDoc 中命名为 accumulator

🙂 预期行为

要么 previousValue 参数应该在 JSDoc 中命名为 previousValue ,要么 callbackfn 的参数应该被重命名为 accumulator ,以避免混淆。
