Faster, smaller `isEqual`

toastal commented 2 years ago

The deep-equal dependency is both slower than fast-deep-equal and has a number of obsolete dependencies to polyfill browsers and Node versions that this project doesn’t target.

To visualize the chain of dependencies deep-equals adds to your project (requires JS enabled): https://npmgraph.js.org/?q=fontkit This would move from around 61 dependencies to 12 (& 11kb Gzip’d).

Moving to fast-deep-equal seems like a win-win.
