**How to add two variable values in JavaScript?**<\/p>\n

Adding two variable values in JavaScript is a fundamental operation that is essential in many programming tasks. It allows you to combine and manipulate numerical or string values to achieve the desired outcome. The process of adding two variables in JavaScript is straightforward and can be done using the addition operator, “+”.<\/p>\n

To add two variable values, follow these simple steps:<\/p>\n

Step 1: Declare and initialize two variables with the desired values.
\nStep 2: Use the addition operator “+” to add the variables together.
\nStep 3: Assign the result to a new variable or use it directly in your code.<\/p>\n

Here’s an example that demonstrates the addition of two variables:<\/p>\n

“`javascript
\nlet num1 = 5;
\nlet num2 = 7;
\nlet sum = num1 + num2;<\/p>\n

console.log(sum);
\n“`<\/p>\n

In this example, we have two variables, “num1” and “num2,” which hold the values 5 and 7, respectively. By using the addition operator, we add the values of num1 and num2 together, resulting in 12. The sum is then stored in the “sum” variable, which we print to the console, displaying 12 as the output.<\/p>\n

The addition operator in JavaScript can also be used to concatenate strings. When encountering string values, the “+” operator will combine them rather than performing arithmetic addition. Let’s see an example:<\/p>\n

“`javascript
\nlet str1 = “Hello, “;
\nlet str2 = “world!”;
\nlet message = str1 + str2;<\/p>\n

console.log(message);
\n“`<\/p>\n

In this example, we have two string variables, “str1” and “str2,” holding the values “Hello, ” and “world!” respectively. By using the “+” operator, we concatenate the two strings, resulting in the message “Hello, world!” being stored in the “message” variable. The message is then printed to the console.<\/p>\n
