stp2y0 CommentsNewscoding, community, css, development, engineering, inclusive, javascript, react, software

UI is the first step before we start typing logic to complete our front end. So we write the markup followed by the essential styles required to get the desired ui. While writing the markup we have to create meaningful class names to address and access the HTML tag and add style to it. With simple UI and distinct tags we can do so more or less easily. While writing repeating and complex UI, giving meaningful and distinct names becomes a disaster as there are only a few generic names.

Hash Map using Javascript

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, programming, software, tutorial, webdev

Introduction A Hash Map, also known as a Hash Table, is a data structure that implements an associative array abstract data type, a structure that can map keys to values. It uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found. The primary advantage of a Hash Map is its efficiency. Operations like inserting a new key-value pair, deleting a key-value pair, and looking up a value given a key are all very fast, often taking constant time on average. Implementing a Simple Hash Map in JavaScript…
