Operators and Expressions

In JavaScript, operators are symbols that perform operations on operands. Expressions are combinations of variables, values, and operators that produce a new value.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations. Here are the common arithmetic operators in JavaScript:

• Addition (+): Adds two operands together.
• Subtraction (-): Subtracts the second operand from the first operand.
• Multiplication (*): Multiplies two operands together.
• Division (/): Divides the first operand by the second operand.
• Modulus (%): Returns the remainder when the first operand is divided by the second operand.

Let's see some examples of using arithmetic operators:

// Arithmetic Operators

​

let num1 = 10;

let num2 = 5;

​

console.log('Addition:', num1 + num2);

console.log('Subtraction:', num1 - num2);

console.log('Multiplication:', num1 * num2);

console.log('Division:', num1 / num2);

console.log('Modulus:', num1 % num2);
