Answer:

# The Statement: Return 2 * 3 + 1, 1 + 5; Returns The Value 12.

The statement given is an example of a mathematical expression in the JavaScript programming language. This expression can be broken down into two distinct parts: the first part is the return statement, which will return the value of the following expression, and the second part is the actual mathematical expression.

## The Return Statement

The return statement is part of the main structure of the JavaScript language and is used to return the value of a given expression. To use the return statement, the programmer must include the word “return” in their code before the information that should be returned. Thus, in the given statement, the word “return” tells the program to return the result of the following expression, which is 2 * 3 + 1, 1 + 5.

## The Math Expression

The math expression given is a basic mathematical expression using two operators, multiplication and addition, and three numbers, two and three, one and five. As stated before, the return statement will return the value of this statement, which is 12. This is calculated by first multiplying the two and three, which results in six plus one, which is seven. Next, this result is added to the one and five, which results in twelve.

## Mathematical Expression Parsers in JavaScript

The statement given is just one small example of a mathematical expression parser, which is a program that can take mathematical expressions, such as the one given and return the value. To build such a parser for your own projects, you can refer to the videos found in the search results such as Writing a Basic Math Expression Parser In JavaScript – YouTube and How to Build a Math Expression Parser in JavaScript. These tutorials and posts will provide you with the necessary information to build your own custom parser. Furthermore, if you wish to include a complex expression parser in your own projects, you can use the Math.js compile() function.

In conclusion, the statement “return 2 * 3 + 1, 1 + 5;” returns the value 12.
