Title: Mastering TypeScript Operators: Comprehensive Guide with Examples

Introduction to TypeScript Operators: Operators are fundamental components of programming languages, enabling developers to perform various operations on values. In TypeScript, operators facilitate arithmetic, comparison, logical, and other operations. In this tutorial, we'll delve deep into TypeScript operators, exploring their types, usage, and providing practical examples to help you harness their power in your coding endeavors.

Table of Contents:

  1. Understanding TypeScript Operators: Operators are symbols that perform operations on operands, such as variables and values.

  2. Arithmetic Operators:

    • Addition (+): Perform addition on numeric values.

       
      let sum: number = 5 + 3; // sum is 8

    • Subtraction (-): Perform subtraction on numeric values.

      let difference: number = 10 - 4; // difference is 6

    • Multiplication (*): Perform multiplication on numeric values.

      let product: number = 3 * 7; // product is 21

    • Division (/): Perform division on numeric values.

      let quotient: number = 20 / 5; // quotient is 4

    • Modulus (%): Calculate the remainder of division.

      let remainder: number = 15 % 4; // remainder is 3

  3. Comparison Operators:

    • Equal (==): Check if values are equal.

      let isEqual: boolean = 5 == 5; // isEqual is true

    • Not Equal (!=): Check if values are not equal.

      let isNotEqual: boolean = 10 != 7; // isNotEqual is true

    • Strict Equal (===): Check if values are equal in value and type.

      let isStrictEqual: boolean = "5" === 5; // isStrictEqual is false

    • Strict Not Equal (!==): Check if values are not equal in value or type.

      let isStrictNotEqual: boolean = "5" !== 5; // isStrictNotEqual is true

    • Greater Than (>), Less Than (<): Compare numeric values.

      let isGreater: boolean = 10 > 7; // isGreater is true

    • Greater Than or Equal To (>=), Less Than or Equal To (<=): Compare numeric values with equality.

      let isGreaterOrEqual: boolean = 10 >= 10; // isGreaterOrEqual is true

  4. Logical Operators:

    • AND (&&): Perform logical AND operation.

      let logicalAnd: boolean = true && false; // logicalAnd is false

    • OR (||): Perform logical OR operation.

      let logicalOr: boolean = true || false; // logicalOr is true

    • NOT (!): Perform logical NOT operation.

      let logicalNot: boolean = !true; // logicalNot is false

Conclusion: Understanding TypeScript operators is essential for manipulating values and performing operations in your code. By grasping arithmetic, comparison, and logical operators, you'll be well-equipped to build complex logic and calculations into your applications. The practical examples and comprehensive explanations provided in this guide will empower you to wield TypeScript operators effectively and create more dynamic and efficient code.
