I'm doing a redux tutorial, and I saw a call like this:

this._render();

and it's defined elsewhere as:

_render() {

    ....

}

What is the underscore _? Why is it used?

This is convention of private methods and variables. In JavaScript there is no real privacy of classes.

It means that you should not use these method (starting with _) out of your object. Of course technically you can, but _ means that you should not.
