[null,null,["Last updated 2023-10-06 UTC."],[],["The `ee.Join.inner` function creates a join between two collections, pairing elements based on matching criteria. Results contain a 'primary' element and a 'secondary' element. Custom names for these properties can be specified using `primaryKey` and `secondaryKey`. An optional `measureKey` allows for storing a measure associated with the join condition in the resulting object. It returns a `Join` object.\n"]]
