difference between req.params and req.query.

Could someone explain what the difference is between req. params and req. query and when it is used. Maybe an example.

Thank you for your answer. I am currently working on my portfolio. I would like to do a search box and filter for my posts or would you like a hint on how to do it. This is my github code https://github.com/bartekfigat/portfolio-website-front-end-and-back-end?files=1. Thanks Clayton

given this route: hello/:param1 and given the following URL: hello/world?id=123&name=joe

req.params will return:

{ param1: 'world' }

req.query will return:

{ id: 123, name: 'joe' }

so, params are before the ? and the keys/values after will be a part of the query object.

NOTE: everything after the ? is called the query string, hence req.query.
