Node.js Operators

Node.js operators include arithmetic and logical extending JavaScript.

Introduction to Node.js Operators

Node.js, built on Chrome's V8 JavaScript engine, extends JavaScript by providing additional APIs for server-side development. As such, Node.js retains the same operator functionality as JavaScript, including arithmetic and logical operators. Understanding these operators is crucial for performing calculations, making decisions, and controlling the flow of your Node.js applications.

Arithmetic Operators

Arithmetic operators are used for performing mathematical calculations. They include:

Addition (+): Adds two operands.
Subtraction (-): Subtracts the second operand from the first.
Multiplication (*): Multiplies two operands.
Division (/): Divides the first operand by the second.
Modulus (%): Returns the remainder of a division operation.
Increment (++): Increases an operand by one.
Decrement (--): Decreases an operand by one.

Logical Operators

Logical operators are used to combine multiple conditions. They include:

AND (&&): Returns true if both operands are true.
OR (||): Returns true if at least one of the operands is true.
NOT (!): Inverts the boolean value of the operand.

Comparison Operators

Comparison operators are used to compare two values. They include:

Equal (==): Checks if two values are equal.
Strict Equal (===): Checks if two values are equal and of the same type.
Not Equal (!=): Checks if two values are not equal.
Strict Not Equal (!==): Checks if two values are not equal or not of the same type.
Greater Than (>): Checks if the left operand is greater than the right.
Less Than (<): Checks if the left operand is less than the right.
Greater Than or Equal To (>=): Checks if the left operand is greater than or equal to the right.
Less Than or Equal To (<=): Checks if the left operand is less than or equal to the right.

Conclusion

Node.js operators play a fundamental role in building applications by allowing developers to perform various operations like calculations, comparisons, and logical evaluations. Understanding these operators not only enhances your ability to write efficient code but also lays the groundwork for more complex programming concepts that you will encounter as you continue learning Node.js.
