フィボナッチ数列は再帰関数の題材として適切なのか |
https://qiita.com/cohey0727/items/117b55cf73c7784359c0
|
これでスタックオーバーフロー問題も克服できたかに思えますが普通にfor文で書いてみる先程の再帰末尾による最適化に対応する際に「第k項と第k項の計算結果用いて第k項を求めるという処理を、kからkn第n項が求まるまで繰り返す」という考え方でプログラムを書きました。 |

TIL: IntersectionObserver Class in JavaScript |
https://dev.to/hirozed/til-intersectionobserver-class-in-javascript-53e2

TIL IntersectionObserver Class in JavaScriptOkay this was a few days ago but ️ Over the last week I ve been devouring The Complete JavaScript Course as a way to Get over my fear of JavaScript that s a post for a later time and Ensure my current carrer as a WordPress developer doesn t stay stuck in the pre Gutenberg world that s also another tale for another time The course itself was fantastic and has put me in a better place mentally and emotionally to take on JS Gutenberg projects There was one section that I wanted to write about today It s a feature that I d never heard of before and would solve some past issues I ve seen at work regarding components of a websites sliding into view and triggering an action It s the IntersectionObserver class The JavaScript IntersectionObserver class which is part of the Intersection Observer API can be used to indicate when a portion of a website scrolls a specified distance down the page or within reach of an element From there you can do wonderful things Set the navigation bar to stick to the top of the page when scrolling past a certain point Lazy load images when or before the come into view Ease sections into view on scroll Below is an example of a sticky navigation from the class s Github repository The Complete JavaScript Course section Advanced DOM and Events credit Jonas Schmedtmann Sticky navigation Intersection Observer API Get the first section of content based on the header classconst header document querySelector header Get the height of the navigation barconst navHeight nav getBoundingClientRect height Add or remove the sticky class to the nav bar based on the entries retrieved from the IntersectionObserver class const stickyNav function entries There is only one header so we don t need to loop and can deconstruct the array const entry entries This is where the magic happens When the header is past the viewport add the sticky class Else when it comes back into view remove the class if entry isIntersecting nav classList add sticky else nav classList remove sticky Calling the IntersectionObserver class const headerObserver new IntersectionObserver stickyNav root null Declaring null uses the entire viewport threshold The percentage of the header to come into view rootMargin navHeight px The offset based on the nav bar s height Get some popcorn the fun is about to start headerObserver observe header I also want to point out getBoundingClientRect This function provides the size of an element and where it s located in relation to the viewport In the example above Jonas only uses the height value but you can grab the size and the distance from the viewport as well Learning about the Intersection Observer API was an unexpected and exciting piece of the huge amount of information I downloaded into my brain I can see using the API as a much more reliable method for detecting when sections of the site come into and out of view and replacing a placeholder with a higher quality image Causing text to zoom in when the container div scrolls into view The possibilities are endless |

Week 2 of my 100daysofcode Challenge |
https://dev.to/jpchreim/week-2-of-my-100daysofcode-challenge-3jab
|
Week of my daysofcode ChallengeIt has been weeks since I started the days of code challenge in which I decided to study and code for at least an hour per day Allow me to enroll my achievements for the last week I ve completed the basic course in Responsive WEB Design and surprisingly I ve found that I can acquire a certificate from FreeCodeCamp if I managed to submit projects From my point of view this certificate is a great opportunity because FreeCodeCamp is a well known site and a certificate from it will bring a value to my profile We should constantly practice what we learned as learning without practicing isn t enough The first project was a tribute page I didn t encounter any difficulties in doing it and that s because I ve planned everything before coding In the second project I had to create a form which users should submit their information Unluckily I couldn t manage to finish it as I had to return my laptop to the dealer because of a camera issue and didn t take any backup of the projects that I m working on Thanks to that I found out the importance of creating GitHub repositories for each project and to keep it updated This issue didn t stop me from continuing my daysofcode journey so I took a break from these projects until my laptop returns and I started with JavaScript which I hardly know how to practice it I ve learned the fundamentals and then jumped to Object manipulating It wasn t something new as my first programming language was Java an OOP but I was surprised with how easy JS is with objects I m currently on challenge number out of on FreeCodeCamp after that I ll start with ES something I heard quite a little about but never had the opportunity to know what is it and why when we use it How about you Are you doing the daysofcode challenge If so where did you reach |
