Technical concepts refer to ideas, principles, and theories related to a particular field of study or work.

• Technical concepts are essential for understanding and applying technical skills.

• They provide a foundation for problem-solving and decision-making in technical fields.

• Examples of technical concepts include programming languages, network protocols, and database management systems.

Various methods exist to compare two objects, including equality checks, hash codes, and deep comparisons.

• Equality Check: Use '==' or '===' in languages like JavaScript to check if two objects are the same instance.

• Property Comparison: Compare properties of objects manually, e.g., 'obj1.name === obj2.name'.

• Deep Comparison: Use libraries like Lodash's 'isEqual' to compare nested objects.

• Hash Code Comparison: Generate hash codes for objects and compare them for quick checks.

Recursion in C language is a programming technique where a function calls itself to solve a problem.

• Recursion involves breaking down a problem into smaller subproblems and solving them recursively.

• A base case is needed to stop the recursion and prevent infinite loops.

• Example: Factorial calculation using recursion - int factorial(int n) { return (n == 0) ? 1 : n * factorial(n-1); }
