π5 Steps to Learn Data Structures & Algorithms (DSA) Effectively
1. Master the Basics π
Start with understanding core concepts like arrays, linked lists, stacks, and queues. Build a strong foundation before moving on to complex topics.
2. Learn Time and Space Complexity β±οΈ
Understanding Big-O notation is crucial to analyze the efficiency of algorithms. Focus on best, worst, and average cases to make better decisions.
3. Practice Coding Problems π»
Platforms like LeetCode, Codeforces, and HackerRank are perfect for practicing real-world problems. The more you code, the better you get!
4. Understand Algorithms βοΈ
Study key algorithms like sorting, searching, and dynamic programming. Learn how to apply them in different scenarios to solve problems efficiently.
5. Consistency is Key
π Set a routine to practice daily, even if it's just for 30 minutes. Consistency will lead to improvement and mastery over time.

#TechTrivia #GoogleHistory #FunFact
Google was almost called Backrub when it first started! π²
The name came from its focus on analyzing backlinks to measure a website's importance. But imagine saying, "Let me Backrub that!" π Doesn't quite have the same ring, does it?
Luckily, they switched it to Google, inspired by the term googol (the number 1 followed by 100 zeros), representing their mission to organize an endless amount of information! πβ¨

π Web Tip: Why You Should Add Version Numbers to Your CSS & JavaScript Files π§βπ»
When working on a website, adding version numbers to your CSS and JS files is crucial! Here's why:
π‘ Tip: Use a query string with each file update like style.css?v=1.3. You can automate versioning with build tools!

When working on a website, adding version numbers to your CSS and JS files is crucial! Here's why:
1οΈβ£ Cache Busting:
Browsers cache your files to improve performance. But this can be problematic when you update your CSS/JS. By adding a version number (e.g., style.css?v=1.2), you ensure that users always get the latest version, not a cached one.
2οΈβ£ Easy Updates:
When you release a new update, changing the version number guarantees that users will fetch the newest files instead of relying on the old cached versions.
3οΈβ£ Debugging Made Easy:
Versioning helps identify which version of a file is causing issues, making debugging simpler.
π‘ Tip: Use a query string with each file update like style.css?v=1.3. You can automate versioning with build tools!

π JavaScript Strict Mode:
Did you know JavaScript has a "strict mode" that helps you write safer and more optimized code? π
What is 'use strict'?
Adding 'use strict'; at the top of your script or function enforces stricter parsing and error handling, preventing common mistakes.
Benefits of Strict Mode:
βοΈ Catches silent errors by turning them into throw errors
βοΈ Prevents accidental global variables
βοΈ Disallows duplicate parameter names
βοΈ Makes eval() and arguments safer
βοΈ Restricts deprecated features
How to Use It?
Simply add this at the beginning of your script or function:
π Pro Tip:
Always use strict mode for cleaner, more reliable JavaScript!
