Js interview #1 : var, let, and const in JavaScript – What's the Difference?

JavaScript variables can be declared using var, let, or const, with differences in scope, hoisting, reassignment, and more.
1. Scope: var is function-scoped, while let and const are block-scoped.
2. Hoisting: var is hoisted and initialized, while let and const are hoisted but not initialized.
3. Redeclaration & Reassignment: var allows both redeclaration and reassignment, let allows reassignment but not redeclaration, and const allows neither.
4. Temporal Dead Zone (TDZ): Variables declared with let and const have a Temporal Dead Zone where they cannot be accessed before declaration.

String Minus Operation In Java

Java does not support a native minus (-) operator for strings like in some scripting languages but simulations can be achieved by removing substrings or characters from other strings.
Common use cases for string manipulation in Java include removing specific words/characters, trimming suffixes/extensions from filenames, and deleting defined patterns.
Java lacks a direct - operator for strings, thus methods like replace(), replaceAll(), replaceFirst(), and substring are used for string manipulation.
The only supported string operator in Java is the + operator for concatenation, while methods like replace(), substring(), and replaceAll() aid in achieving 'minus' operations.
Various methods, including replace(), replaceAll(), substring(), and replaceFirst(), can be utilized to simulate 'minus' operations on strings in Java.
The Java class StringMinusOperations provides code examples for removing characters, substrings, or suffixes from strings using different methods like replace, substring, and Java Streams.
The code examples demonstrate removing characters like 'a', 'b', 'n', a known suffix like '.txt', and the first occurrence of a substring like 'apple'.
A custom solution using Java Streams is showcased to remove specific characters like 'a' and 'e' from a string, displaying an alternative functional style approach.
Java developers can efficiently perform 'minus' operations on strings by understanding methods like replace, replaceAll, replaceFirst, and substring, offering flexibility in string manipulation.
The article concludes by emphasizing the importance of mastering string manipulation techniques in Java to handle diverse challenges with clarity and precision.

Golden powers revisited

A post revisiting the concept of golden powers, which are nearly integers, has been published.
The post explains why golden powers are close to integers using equations involving the golden ratio and the smaller root of x² − x − 1 = 0.
The equations reveal that the integers referred to in relation to golden powers are actually Fibonacci numbers.
The approximation for φn as an integer is nearly the sum of the (n + 1)st and (n − 1)st Fibonacci numbers, with the error decreasing exponentially with alternating signs.
