Benchmark: string-interpolation-vs-concatenation multi variable

Script Preparation code:

var luckyNumber = Math.round(Math.random() * 100);
var uluckyNumber = Math.round(Math.random() * 100);
var anotherNumber = Math.round(Math.random() * 100);

Tests:

string-interpolation
`your lucky number for today is: ${luckyNumber} and unlucky number: ${uluckyNumber} and just another number : ${anotherNumber}`
string-concatenation
'your lucky number for today is: ' + luckyNumber + ' and unlucky number: ' + uluckyNumber + ' and just another number : ' + anotherNumber

I'll explain the provided benchmark and its options.

**Benchmark Overview**

The provided benchmark measures the performance difference between two approaches to string concatenation in JavaScript: template literals (interpolation) and traditional string concatenation using the `+` operator.

**Options Compared**

Two test cases are compared:

1. **String Interpolation**: Template literals (`${}`) are used to create strings. This approach is more readable and concise, but its performance might be affected by the complexity of the expression.
2. **String Concatenation**: Traditional string concatenation using the `+` operator is used to create strings.

**Pros and Cons**

* **String Interpolation (Template Literals)**:
	+ Pros: More readable and concise code, better support for dynamic values, and less error-prone than traditional concatenation.
	+ Cons: Might have performance overhead due to the complexity of the expression, and some older browsers may not support template literals.
* **String Concatenation**:
	+ Pros: Well-supported by most modern browsers and can be faster than template literals for simple expressions.
	+ Cons: Less readable and more prone to errors when dealing with dynamic values or complex expressions.

**Library and Special JS Feature**

There is no library used in this benchmark, but it does utilize a special JavaScript feature: **Template Literals (String Interpolation)**. Template literals were introduced in ECMAScript 2015 (ES6) and have become a standard feature in modern JavaScript.

**Other Considerations**

When writing string concatenation code, it's essential to consider the following:

* Use `+` operator or template literals instead of `+=` or other string manipulation methods.
* Avoid using `String.fromCharCode()` or other low-level string creation methods, as they can be slower and less efficient than modern string concatenation approaches.

**Alternatives**

If you need to measure performance for different string concatenation approaches, consider the following alternatives:

1. Use a library like Lodash's `template` function, which provides a more readable way to create strings using template literals.
2. Utilize a benchmarking framework like Jest or Mocha, which provide built-in support for measuring execution time and optimizing code.
3. Consider using a different programming language or framework that offers better string concatenation performance, such as Rust's string interpolation or Python's f-strings.

Keep in mind that the best approach depends on your specific use case and performance requirements.
