This util area contains utility functions, whereas ../lib contains utility components.
Must be invoked with this bound to a React component that is beneath a React Router match, so that this.props.location and this.context.router are both defined.
Takes as its argument an object containing key: value pairs. It transitions to a URL that is the same as the present one except that the specified query parameters are included -- replacing the same-named parameters if they already exist, and adding new parameters where they do not.
For example, if you are at the URL:
http://localhost:3000/users?filters=active.Active&sort=Name
and invoke this function as:
this.transitionToParams({ query: 'water', sort: 'Email' })
The application will transition to the new URL:
http://localhost:3000/users?filters=active.Active&sort=Water&query=Email
The filters query parameter is unaffected (since it was not included in the parameters passed in), the old sort value Name is replaced by the new value Email, and the new parameter query is added with the value water.
