    90s Cursor Effects

    90s Cursor Effects

    Old-school cursor effects for your browser built with modern JS

    "Knowing the codes" used to be all the rage, I want to bring a few back. A repo of the old effects that inspired creativity and the desire to learn at least a little code around the world. Modernized so they're a little more efficient, and just as annoying (and twice as fun) as they were before.

    Functional programming library golang

    Functional programming library golang

    functional programming library for golang

    This library aims to provide a set of data types and functions that make it easy and fun to write maintainable and testable code in Golang. Write many small, testable, and pure functions, i.e. functions that produce output only depending on their input and that do not execute side effects. Offer helpers to isolate side effects into lazily executed functions (IO). Expose a consistent set of compositions to create new functions from existing ones. For each data type, there exists a small set of composition functions. These functions are called the same across all data types, so you only have to learn a small number of function names. ...

    redux-saga

    redux-saga

    An alternative side effect model library for Redux applications

    redux-saga is a library that aims to make application side effects (i.e. asynchronous things like data fetching and impure things like accessing the browser cache) easier to manage, more efficient to execute, easy to test, and better at handling failures. The mental model is that a saga is like a separate thread in your application that's solely responsible for side effects. redux-saga is a redux middleware, which means this thread can be started, paused and cancelled from the main application with normal redux actions, it has access to the full redux application state and it can dispatch redux actions as well. ...
