     	return xs.map(get([x])).filter(y => y !== null).flat();

Tests:

jsonata
var jsonataResult = jsonata('subEvent.offers.acceptedPaymentMethod').evaluate(result).join(' ');
simple
var simpleResult = get(['subEvent','offers','acceptedPaymentMethod'])(result).join(' ');
jspath
var jsPathResult = JSPath.apply('.subEvent.offers.acceptedPaymentMethod', result).join(' ');
jmespath
var jmespathResult = jmespath.search(result, 'subEvent[].offers[].acceptedPaymentMethod[]').join(' ');
control
result.subEvent.map(s => s.offers.map(o => o.acceptedPaymentMethod)).flat(2).join(' ')
jspath+predicates
var jsPathResult = JSPath.apply('."imin:aggregateOffer".publicAdult{.price > 0 && .priceCurrency > "."}[-1]', result);
meta-index
var jsPathResult = JSPath.apply('."imin:index"(.subClass | .enumeration).."imin:item"', window.imin.v2.meta);
meta-nameonly
var jsPathResult = JSPath.apply('."imin:index"(.subClass | .enumeration)..name', window.imin.v2.meta);
meta-flatten
var result = flattenCollection(window.imin.v2.meta);

The provided JSON represents a set of benchmark tests for comparing different libraries and approaches to query JSON data in JavaScript.

**Library Overview**

1. **jsonata**: A JSON querying language that allows you to query JSON data using a simple syntax.
2. **simple**: A custom implementation by the creator of MeasureThat.net, which uses a reduce function to traverse the JSON data.
3. **jspath**: A library inspired by XPath (XML Path Language) that allows you to query JSON data using a similar syntax to XML.
4. **jmespath**: A JSON-specific variant of XPath that is optimized for querying JSON data.

**Library Comparison**

Each test compares the performance of one or more libraries and approaches when querying JSON data. The results are represented as a series of objects, each containing information about the benchmark run, such as:

* `TestName`: The name of the benchmark test.
* `RawUAString`: The User Agent string reported by the browser during the benchmark run.
* `Browser`, `DevicePlatform`, and `OperatingSystem`: Information about the browser and device used during the benchmark run.
* `ExecutionsPerSecond`: The number of executions per second for each library or approach.

**Approach Comparison**

The tests compare different approaches to querying JSON data, including:

1. **jspath**: Uses a syntax similar to XML XPath to query JSON data.
2. **jmespath**: Optimized for querying JSON data using a syntax inspired by XPath.
3. **simple**: A custom implementation by the creator of MeasureThat.net, which uses a reduce function to traverse the JSON data.
4. **jsonata**: Uses a simple syntax to query JSON data.

**Key Insights**

* jmespath and jspath are optimized for querying JSON data and outperform the other libraries in many cases.
* jsonata is relatively slow compared to the other two, but still performs well.
* The custom implementation by MeasureThat.net (simple) is slower than jmespath and jspath.

Overall, these benchmarks provide a comprehensive comparison of different libraries and approaches for querying JSON data in JavaScript, allowing developers to choose the best option for their specific use case.
