TypeScript and currying

TypeScript and currying

In functional programming you often want to apply a function partly. A simple example is a function add. It would be nice if we could use add like:

var add10To = add(10);
var res = add10To(5); // => 15

You appear to be creating a new IDE...
You appear to be advocating a new:

[ ] Garbage collection is free
[ ] Computers have infinite memory
[ ] Nobody really needs:

React Warning - Invalid access to component property

You're probably getting this warning because you're accessing methods on a component before it gets mounted. This will be soon be an unsupported use case.

The component that gets created by invoking the convenience constructor MyComponent(props, children) or using the JSX syntax <MyComponent /> is not guaranteed to be the instance that actually gets mounted. It's a description of what the actual mounted instance should look like.


The component also doesn't have access to state or other important information such as the final props. As a consequence you shouldn't be calling custom methods on this object.

var MyComponent = React.createClass({
