pure-bind v1.0.1

Pure Bind

Binds argments to functions with memoization of infinite depth.

API

Syntax

bind(fnc, arg1[, arg2[, ...]])

Parameters

fnc

The function to be bound

arg1, arg2, ...

The arguments to bind

Returns

A copy of the function with the arguments bound to it and this set to undefined. If these argument have been bound to the function before, a cached copy with the same reference is returned.

Example usage

import bind from 'pure-bind';

class MyComponent extends React.Component {
    render() {
        return (
            <MySubComponent onClick={bind(setValue, 1)} />
        )
    }
}

No matter how many times MyComponent is rerendered, MySubComponent will always get an onClick prop with the same refernce allowing it to perform a strict equality check in its shouldComponentUpate logic.
