concatenateStrings()

Parameters: str1 (string), str2 (string)

Two strings that are to be combined.

Returns: A new string which is the combination of str1 and str2

In programming, concatenation generally means to stick two things together. In JavaScript, we use the '+' operator to concatenate strings. This function takes two strings as inputs and returns one string which is their combination.

How to Concatenate Strings in JavaScript

Hello there, programmer! Welcome to our blog post. In the steps that follow, we will guide you through programming a function to concatenate strings. This uncomplicated guide will provide clear and simple steps to ensure that you can follow along without any trouble. So, sit back, relax, and let's dive into some coding together.

Step 1: Understanding the Problem

Before starting with the solution, we need to understand what concatenating a string means. Concatenation means joining two or more strings together to form a single string.

var firstString = 'Hello, ';  
var secondString = 'World!';  
var result = firstString+secondString; // 'Hello, World!'  

Step 2: Define the Function

We define our function concatenateStrings(string1, string2) that accepts two parameters: string1 and string2.

function concatenateStrings(string1, string2){ 
   // code here  
}  

Step 3: Implementing the Concatenation Logic

Inside our function, we use the '+' operator to concatenate the input strings and store the result in a variable result.

function concatenateStrings(string1, string2) {  
    var result = string1 + string2;  
    // code here  
}  

Step 4: Return the Result

Finally, we return result from the function.

function concatenateStrings(string1, string2) {  
    var result = string1 + string2;  
    return result;  
}  

Step 5: Calling the Function

To use our function, we call it with the required parameters. In this example, we're passing 'Hello, ' and 'World!' to get the concatenated string.

concatenateStrings('Hello, ', 'World!');  // returns 'Hello, World!'  

Conclusion

The concatenateStrings function is a simple and effective solution to concatenate two strings in JavaScript.

Mathematical principle

The concept of string concatenation in programming doesn't follow any complex mathematical principal. It's simply the operation of combining two strings together into a single entity. In JavaScript, the `'+'` operator is used for this operation. Suppose we have two strings `'Hello'` and `'World'`. On concatenation we get, `'Hello' + 'World' => 'HelloWorld'`
