Benchmark: stringies - MeasureThat.net

Script Preparation code:

const first = "first"
const second = "second"

Tests:

plusOp
const first = "first" const second = "second" let thing = first + ' ' + second;
literal
const first = "first" const second = "second" let thingTwo = `${first} ${second}`;
concat
const first = "first" const second = "second" let mystring = ''.concat(first, ' ', second);

**Overview of the Benchmark**

The provided benchmark, created using MeasureThat.net, tests the performance of different ways to concatenate strings in JavaScript. There are three test cases:

1. `plusOp`: Uses the `+` operator to concatenate two strings.
2. `literal`: Uses template literals (the `${}` syntax) to concatenate two strings.
3. `concat`: Uses the `.concat()` method to concatenate two strings.

**Comparison of Options**

The benchmark tests three different approaches to string concatenation:

1. **Plus Operator (`+`)**: This is a simple and widely supported way to concatenate strings in JavaScript. The pros are that it's easy to use and works in most browsers.
	* Cons: Can lead to performance issues if used excessively, as it creates a new string object on each concatenation.
2. **Template Literals (`${}`)**: This is a more modern way of concatenating strings introduced in ECMAScript 2015 (ES6). The pros are that it's readable and efficient, as it only creates one string object.
	* Cons: May not be supported in older browsers or environments.
3. **`.concat()` Method**: This method is part of the Array prototype and can be used to concatenate strings. The pros are that it's efficient and works well with arrays.
	* Cons: May require an extra step to call the method, which can lead to performance issues if not done correctly.

**Library Used**

None of the test cases uses any external libraries or dependencies.

**Special JS Features or Syntax**

The `literal` test case uses template literals (the `${}` syntax), which is a new feature introduced in ECMAScript 2015 (ES6). Template literals provide a more readable way to concatenate strings and are supported by most modern browsers.

**Other Alternatives**

If you're looking for alternatives to the above approaches, here are some options:

* **String.prototype.push()**: This method can be used to concatenate strings, but it's less efficient than using the `+` operator or template literals.
* **String.prototype +=**: This method is similar to using the `+=` operator, but it's less efficient than using the `+` operator.

In summary, the benchmark tests three different ways to concatenate strings in JavaScript: using the `+` operator, template literals, and the `.concat()` method. Each approach has its pros and cons, and the choice of which one to use depends on your specific use case, performance requirements, and target browser support.
