// Programming languages are languages that instruct the computer to perform tasks

// The function addNumbers adds two numbers
function addNumbers(a, b) {
  return a + b;
}

// Call the function addNumbers and store the result in the variable sum
var sum = addNumbers(5, 3);

// Output the value stored in the variable sum
console.log('What is the value of sum?');

# What are Programming Languages?

Unlike markup languages (languages that represent the structure of data and content) such as HTML, and style sheets (documents that define the style of webpages) such as CSS, **JavaScript** is a `programming language` that instructs a computer to perform tasks.

Since computers are complex digital devices that represent and process data in 0s and 1s, they cannot understand human languages like English, Spanish, or French.

Therefore, a programming language is an intermediary language that both humans and computers can understand.

The example `addNumbers` function takes two `parameters`, a and b, and returns the result of adding these two parameters.

We will explain functions in detail later!

A programming language is a language used to instruct a computer to perform tasks. It sits at an intermediate level that can be understood by both humans and computers.
