[gameroman]

Package to replace

fftjs and fft-js

Suggested replacement(s)

fft.js and fft.ts

Manifest type

preferred (lighter or more modern alternative package)

Rationale

fftjs and fft-js have several dependencies and are unmaintained

fft.js is somewhat maintained

fft.ts is made by me and also supports inputs that are not power of 2

given neither of them have more than 10k downloads, i wonder if its worth adding them.

the replacements already have more usage 🤔

They have ~11k both

Although one of the replacements does have more usage, when someone is choosing a library this would make choosing one simpler
