Aggregation pipelines can get very long, depending on how many stages we need to run. Writing a pipeline is writing code, as you will write it using one of the many MongoDB drivers in your own language. Here we're presenting the examples using JavaScript suitable for the MongoDB shell [mongosh](https://www.mongodb.com/docs/mongodb-shell/), but if you are writing a microservice in Rust, you'll definitely write your pipelines in Rust.

As this is code, we can even add comments (starting with `//`) to our pipelines. Or write functions that take parameters and return a stage. Or unit test our stages.

👐 We can also use `$gte` to get the books with 150 pages or more. Check $gte syntax in the [docucumentation](https://www.mongodb.com/docs/manual/reference/operator/query/gte/) and write an aggregation pipeline to return 15 books from 1985 with more than 150 pages. Show only the `title`, `year`, `totalInventory`, and `available` books (sample doc [here](/docs/simple-queries/project)).
