fast-equals CHANGELOG

3.0.3

• Fix #77 - better circular object validation

3.0.2

• Fix #73 - support comparison of primitive wrappers
• #76 - improve speed and accuracy of RegExp comparison in modern environments

3.0.1

• Fix #71 - use generic types for better type flow-through

3.0.0

Breaking changes

When creating a custom equality comparator via createCustomEqual, the equality method has an expanded contract:

// Before
type EqualityComparator = (objectA: any, objectB: any, meta: any) => boolean;

// After
type InternalEqualityComparator = (
  objectA: any,
  objectB: any,
  indexOrKeyA: any,
  indexOrKeyB: any,
  parentA: any,
  parentB: any,
  meta: any,
) => boolean;

If you have a custom equality comparator, you can ignore the differences by just passing additional undefined parameters, or you can use the parameters to further improve / clarify the logic.

• Add #57 - support additional metadata for custom equality comparators

2.0.4

• Fix #58 - duplicate entries in Map / Set can create false equality success
• #60 - Add documentation for key equality of Map being a part of deepEqual

2.0.3

• Fix #50 - copy-pasta in cacheable check

2.0.2

• Optimize iterables comparisons to not double-iterate
• Optimize loop-based comparisons for speed
• Improve cache handling in circular handlers
• Improve stability of memory by reducing variable instantiation

2.0.1

• Fix #41 - prevent .rpt2_cache directory from being published for better CI environment support (thanks @herberttn)

2.0.0

Breaking changes

• There are longer fast-equals/es, fast-equals/lib, fast-equals/mjs locations
  • Instead, there are 3 builds in dist for different consumption types:
    • fast-equals.js (UMD / browser)
    • fast-equals.esm.js (ESM / module)
    • fast-equals.cjs.js (CommonJS / main)
• There is no default export anymore, only the previously-existing named exports
  • To get all into a namespace, use import * as fe from 'fast-equals

Updates

• Rewritten completely in TypeScript
• Improve speed of Map / Set comparisons
• Improve speed of React element comparisons

Fixes

• Consider pure objects (Object.create(null)) to be plain objects
• Fix typings for createCustomEqual

1.6.3

• Check the size of the iterable before converting to arrays

1.6.2

• Fix #23 - false positives for map
• Replace uglify with terser
• Use rollup to build all the distributables (main, module, and browser)
  • Maintain lib and es transpilations in case consumers were deep-linking

1.6.1

• Upgrade to babel@7
• Add "sideEffects": false to package.json for better tree-shaking in webpack

1.5.2

• Improve speed of object comparison through custom hasKey method

1.5.1

• Fix lack of support for unicode and sticky RegExp flag checks

1.5.0

• Add circularDeepEqual and circularShallowEqual methods
• Add meta third parameter to comparator calls, for use with createCustomEqual method

1.4.1

1.0.2
