Of course. Based on the CodeHS exercise “8.3.7: Exclamation Points,” the goal is to write a JavaScript function that adds three exclamation points to the end of a given string.<\/p>\n\n\n\n
Here is the correct code for the solution:Generated javascript<\/p>\n\n\n\n
function addExclamationPoints(str) {\n return str + \"!!!\";\n}<\/code><\/pre>\n\n\n\n
Explanation<\/h3>\n\n\n\n
This exercise is a fundamental practice in JavaScript that teaches you how to define functions, handle parameters, and manipulate strings. The objective is to create a function named addExclamationPoints that takes a single piece of text, known as a string, and returns that same string with “!!!” appended to its end.<\/p>\n\n\n\n
The solution begins with the function keyword, which is how you declare a new function in JavaScript. Following this keyword is the name of our function, addExclamationPoints. The name is chosen to clearly describe what the function does. Inside the parentheses (str), we define a parameter. A parameter is a placeholder for a value that will be provided when the function is called. In this case, str will hold the input string that we want to modify.<\/p>\n\n\n\n
The core logic of the function is contained within the curly braces {}. The single line of code, return str + “!!!”;, accomplishes the entire task. Let’s break it down. The return keyword is essential; it specifies the value that the function should send back as its result. Without it, the function would run but produce no output.<\/p>\n\n\n\n
The expression str + “!!!” demonstrates string concatenation. In JavaScript, when the + operator is used between two strings, it joins them together to form a new, single string. It takes the original string value stored in the str parameter and attaches the literal string “!!!” to it. For example, if the function were called with the input “Hello”, str would be “Hello”, and the function would return “Hello” + “!!!”, resulting in “Hello!!!”. This concise solution effectively uses basic JavaScript principles to solve the problem.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
