Java Predicate is a functional interface that is part of Java.util.function package. It was introduced in Java 8. It represents a single argument function that returns a boolean value. A Predicate takes an input and returns either true or false, depending on the condition that is specified in the function. Using predicate to check if Continue Reading »
Memoization is a powerful technique used in computer science to optimize the performance of functions that are called repeatedly with the same arguments. In JavaScript, memoization is particularly useful for expensive computations that involve complex algorithms or data structures. At its core, memoization involves caching the result of a function based on its input arguments. Continue Reading »
Before discussing into JavaScript pass-by-reference or pass-by-value function, it is known about the difference between primitive and non-primitive. Primitive Values: – Data Types string, number, null, undefined, symbols, and Boolean are primitive values. Primitive values are passed by value in JavaScript. Non Primitive Values: – object, array, and function are non-primitive values. All objects and Continue Reading »

A unary function is a mathematical function that takes only one argument or input. It is a function of a single variable, which means that it operates on a single operand. The term “unary” comes from the Latin word “unarius” meaning “consisting of one.” For example, the function f(x) = x^2 is a unary function Continue Reading »
The actuator is mainly used to expose operational information about the running application — health, metrics, info, dump, env, etc. It uses HTTP endpoints or JMX beans to enable us to interact with it. Once this dependency is on the classpath, several endpoints are available for us out of the box. The main benefit of Continue Reading »
In Java, HashMap is a widely used data structure that stores elements in key-value pairs. It provides constant-time performance for basic operations like adding, removing, and accessing elements.
