本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。 MIT-0

契约

  1. abs returns absolute value for positive, negative, and signed zero inputs
  2. floor returns the largest integer less than or equal to a given number
  3. isFinite returns true only for finite number primitives and false for non-numbers and infinities
  4. isInteger returns true for integer numbers and false for non-integers and non-numbers
  5. isNaN returns true exclusively for NaN and false for non-NaN values including strings
  6. isNegativeZero correctly distinguishes -0 from +0 and other values
  7. max and min compute multi-argument numeric extremums correctly
  8. mod computes mathematical positive modulo for positive and negative numbers
  9. pow computes exponentiation base to power
  10. round returns the value of a number rounded to the nearest integer
  11. sign returns correct numeric sign for positive, negative, zero, and infinity
  12. constants expose maxArrayLength, maxSafeInteger, and maxValue with exact standard numeric values
