JavaScript memory management

  • JavaScript memory leaks can cause web apps to slow down, act weird, or crash over time.
  • JavaScript is a garbage-collected language that automatically frees up memory not in use through the garbage collector.
  • Memory leaks occur when memory that should be cleaned up is still being held onto by the code, leading to performance issues.
  • These forgotten bits of memory accumulate over time and can significantly impact the app's performance.

THE IMPORTANCE OF ASYNC PROGRAMMING

  • Short runtime is crucial for software programs, especially those working with large datasets.
  • Async programming can significantly reduce runtime by allowing threads to perform other tasks while waiting for responses.
  • For small datasets, the impact of async programming may not be significant, but for larger datasets, it becomes necessary.
  • Async programming overcame the limitation of threads idling while waiting for responses, improving efficiency in handling tasks asynchronously.

Kotlin's Performance and What it Means

  • Kotlin, a modern programming language known for its concise syntax and Java interoperability, is examined for its performance compared to other languages.
  • In benchmarks, Kotlin JVM consistently ranks lower in performance than other languages, even after enabling compiler optimizations.
  • The benchmarks app runs programs simultaneously 25 times to calculate averages and minimum times, revealing Kotlin's slower overall performance.
  • Analyzing a Bubble Sort benchmark in Kotlin Native shows decent speed but lags behind in minimum times, indicating room for improvement.
  • Decompilation of Kotlin code reveals runtime metadata comparison for type/version correctness, impacting program performance.
  • Kotlin's runtime features like metadata comparison and Intrinsics for null safety add overhead, potentially slowing down program execution.
  • The analysis suggests that while Kotlin is a promising language, its current performance may need enhancements for higher efficiency.
  • Despite the trade-offs for safety and correctness features, Kotlin's performance could see improvements in the future.

My Journey Through `this` in JavaScript: From Confusion to Clarity

  • When learning JavaScript, understanding 'this' can be confusing due to its dynamic nature.
  • this in JavaScript refers to the execution context of a function, determined by the call site.
  • JavaScript has three main execution contexts: Global, Function, and Eval.
  • Four primary ways of setting 'this' are Default, Implicit, Explicit, and new Binding.
  • Arrow functions in JavaScript do not have their own 'this' and inherit it from the lexical scope.
  • Common pitfalls with 'this' include losing context in callbacks and nested functions.
  • Understanding 'this' involves recognizing call sites and using tools like arrow functions and bind.
  • Practice and experimentation are key to mastering the behavior of 'this' in JavaScript.
  • Overall, 'this' in JavaScript is a powerful tool once its behavior is understood and applied correctly.
  • To dive deeper into 'this' in JavaScript, resources like MDN and 'You Don’t Know JS: this & Object Prototypes' are recommended.

Types from Typescript

  • Typescript introduces various types for defining variables:
  • Primitives types like Boolean, Number, and String are similar to JavaScript.
  • Typescript also includes composed types such as Array, Tuple, Enum, and Object.
  • The Any type represents any other type.
  • Null and Undefined have specific meanings where Null signifies empty or reset value, while Undefined is for unset values.
  • Unknown type is used when the type of data from external sources is unknown.
  • Void represents no type and is used for functions that don't return anything.
  • Never type signifies a type that never occurs, often seen in functions that always throw errors.
  • Generic type (T) allows accepting any type while enforcing type checking.
  • Unions and Intersections are essential for type declaration in Typescript.
