record.get() function

record.get() is experimental and subject to change at any time. By using this function, you accept the risks of experimental functions.

record.get() returns a value from a record by key name or a default value if the key doesn’t exist in the record.

This is an interim solution for the exists operator’s limited use with records outside of a stream of tables. For more information, see influxdata/flux#4073.

exampleRecord = {foo: 1.0, bar: "hello"}

record.get(r: exampleRecord, key: key, default: "")// Returns 1.0
