Benchmark: Lodash throttle test

Tests:

Lodash
// call once every 1000ms var sec = _.throttle(function () { console.log('every second'); }, 1000); // call every 100ms var hundredMS = _.throttle(function () { console.log('every one hundred ms'); }, 100); // a loop for every 33ms var loop = function () { setTimeout(loop, 33) sec(); hundredMS(); }; // start loop loop();
Native
var throttle = function (func, rate) { var lastTime = new Date(); func = func || function () {}; rate = rate || 1000; // the inner method return function () { var now = new Date(); if (now - lastTime >= rate) { func(); lastTime = now; } }; }; var sec = throttle(function () { console.log('one sec'); }, 1000); // using it in a loop var loop = function () { setTimeout(loop, 33); sec(); }; loop();

**Overview of the Benchmark**

The provided benchmark measures the performance of two approaches for implementing a throttle function in JavaScript:

1. **Lodash's `throttle` function**: A utility function from the popular JavaScript library Lodash that throttles the execution of a given function.
2. **A custom implementation of a throttle function**: A native JavaScript implementation of a throttle function.

**What is being tested?**

The benchmark tests the performance of both approaches in different scenarios:

* Throttling a function to be called every 1 second (Lodash's `throttle` function).
* Throttling a function to be called every 100 milliseconds (Lodash's `throttle` function).
* Creating a loop that calls two throttled functions every 33 milliseconds, which are themselves calling the original throttle functions.

**Options compared**

The benchmark compares the performance of:

1. **Lodash's `throttle` function**: A pre-built utility function from Lodash that performs the throttle operation.
2. **Custom implementation of a throttle function**: A native JavaScript implementation of a throttle function, which allows for more fine-grained control over the throttling behavior.

**Pros and Cons**

* **Lodash's `throttle` function**:
	+ Pros: Convenient and easy to use, optimized for performance.
	+ Cons: Adds an additional dependency on Lodash, may have slower startup times due to the import.
* **Custom implementation of a throttle function**:
	+ Pros: More control over the throttling behavior, potentially faster startup times since it doesn't require importing Lodash.
	+ Cons: Requires more manual implementation and maintenance effort.

**Library used**

The benchmark uses Lodash's `throttle` function in one of the test cases. Lodash is a popular JavaScript library that provides a wide range of utility functions for tasks such as array manipulation, string manipulation, and more. The `throttle` function is specifically designed to throttle the execution of a given function at a specified rate.

**Special JS feature or syntax**

There are no special JavaScript features or syntax used in this benchmark.

**Other alternatives**

For implementing throttle functions, other popular libraries or frameworks that provide similar functionality include:

* **Mochas `debounce` and `throttle` functions**: Similar to Lodash's throttle function, but with different default behavior.
* **React's `useCallback` and `useEffect` hooks**: Can be used to implement throttle-like behavior in React applications.

In summary, the benchmark provides a simple yet effective way to compare the performance of two approaches for implementing throttle functions: Lodash's pre-built `throttle` function and a custom implementation. The results can help developers choose between these options based on their specific use case requirements.
