Common Coding Mistakes to Avoid
Even experienced programmers make mistakes.
Ensure all variables are declared and initialized before use.
Be mindful of JavaScript's automatic type conversion, which can lead to unexpected results.
Understand the difference between global and local scope to avoid unintended variable access.
Carefully review your code for logical inconsistencies that might lead to incorrect output.
Pay attention to array indices and loop conditions to prevent errors in indexing and iteration.
Avoid creating loops that never terminate due to incorrect conditions or missing exit points.
Example:
// Undefined variable error
let result = x + 5; // Assuming x is not declared
// Type coercion error
let age = "30";
let isAdult = age >= 18; // Age will be converted to a number
By being aware of these common pitfalls, you can write more robust and error-free code.

Logical errors:
Carefully review your code for logical inconsistencies that might lead to incorrect output.
Off-by-one errors:
Pay attention to array indices and loop conditions to prevent errors in indexing and iteration.
Infinite loops:
Avoid creating loops that never terminate due to incorrect conditions or missing exit points.
Example:
// Undefined variable error
let result = x + 5; // Assuming x is not declared
// Type coercion error
let age = "30";
let isAdult = age >= 18; // Age will be converted to a number

🚀 PERFORMANCE TUNING: Boost Your System Like a Pro! ⚡️
Is your application slow? Facing database bottlenecks? Or maybe network issues? Performance tuning is the key! Here’s a breakdown of essential optimization areas to supercharge your system:
🔹 Code Tuning 🖥
Optimize your code by managing CPU, memory, and other resources efficiently. A few tweaks can make a BIG difference!
🔹 Infrastructure Tuning 🏗
Benchmark, scale, and optimize storage to ensure your hardware and cloud infrastructure are performing at their best.
🔹 Architecture Tuning ☁️
Implement caching, loose coupling, and asynchronous processing for a seamless and scalable system.
🔹 Configuration Tuning ⚙️
Fine-tune your app's settings for maximum efficiency—master configuration tuning is crucial!
🔹 Network Tuning 🌐
Reduce latency, optimize traffic flow, and secure your network with firewall & DNS adjustments.
🔹 Database Tuning 🗄
Optimize queries, indexes, and partitions to speed up data retrieval and improve overall DB performance.
