Question

Implement Promise based memoization with a given cache size behaving as an LRU cache with an expiry time and auto cache burst.

Answer

First, what we have to do is breakdown the terms in the problem statement to understand what is going on and what we are asked to do.

1. Promise based memoization: Memoization is one of the ways we can improve the performance of functions by eliminating redundant calls. Memoization is a technique where we store the results of a function call in a cache and return the result from the cache if the function is called again with the same arguments.

animation-name,This is the name of the keyframe you want to bind to the selector. Keep an eye on this one when you read the keyframes section below.

animation-timing-function,"The speed curve of the animation. Eg: linear, ease, ease-in, ease-out, ease-in-out, step-start, step-end, steps(int,start|end), cubic-bezier(n,n,n,n), initial, inherit"
animation-delay,"Defined in seconds (s) or milliseconds (ms), it’s the length of a delay before the animation will start. Note: If given a negative value, it will start playing as if it had been playing for a given amount of time."

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

Today, single page web apps are driving many websites that we use each and every day. Instead of having your browser request a new web page for each and every action you perform on a web page, single page web apps may load all in one request to smoothly and quickly transition with every action you perform.

When building single page web apps, you may decide to retrieve all of the HTML, CSS and Javascript with one single page load or dynamically load these resources as the user moves about your site. Either way, it can be a pain to bundle all of these assets together for the end user to download from your web server. This is where webpack comes into play.

webpack does all of the heavy lifting bundling all of your HTML, CSS and Javascript together. If you write your site all from scratch or depend on dependencies from npm, webpack takes care of packaging it all together for you. It has the ability to take your single page web app, cut out all of the code you don't need, then packa
