Performing Arithmetic Operations in JavaScript: A Beginner's Guide

In JavaScript, arithmetic operations are used to perform mathematical calculations and manipulate numerical values. The basic arithmetic operations include

Sno	Operator	Usage
1.	+	Addition
2.	-	Subtraction
3.	*	Multiplication
4.	**	Exponentiation (2016)
5.	/	Division
6.	%	Modulus (Remainder)
7.	++	Increment
8.	--	Decrement

Addition (+): This operator is used to add two or more numbers together. For example, 4 + 3 will give the result of 7.
Subtraction (-): This operator is used to subtract one number from another. For example, 10 - 3 will give the result of 7.
Multiplication (*): This operator is used to multiply two or more numbers together. For example,4 * 3 will give the result of 12.
Division (/): This operator is used to divide one number by another. For example, 10 / 5 will give the result of 2
Modulus (%): This operator is used to find the remainder when one number is divided by another. For example, 10 % 3 will give the result of 1.
Exponentiation (**): This operator is used to raise a number to a certain power. For example, 2 ** 4 will give the result of 16.

The above code is written in JavaScript and it performs various arithmetic operations on two variables, a and b. The variables a and b are declared using the let keyword and are assigned the values 100 and 20, respectively.

A new variable c is declared using the let keyword and is used to store the result of the arithmetic operations.

The first operation is the addition of a and b and the result is assigned to c. Then the subtraction of b from a and the result is assigned to c. Then the multiplication of a and b and the result is assigned to c. Then the division of a by b and the result is assigned to c. Then the modulus of a by b and the result is assigned to c.

Then the operation 2 raised to the power of 3, which gives the result 8. Then the operation of incrementing the value of a and the result is assigned to c. Then the operation of decrementing the value of b and the result is assigned to c.

Finally, the console.log() function is used to output the final value of c to the console, which will be the result of the last operation performed, which is decrementing the value of b.
