There may be many different reasons why you’d want to swap two variables be it just changing two item’s location in an array or when sorting collections. The traditional way is just define a new variable, assign one value to it, put one of the items in the old place, then put the temp variable back in the new place. But my question is, is that the only way?
There are many different sorting algorithms out there such as quick sort, merge sort, insertion sort, bubble sort, etc., that could be useful in our day to day life, writing code which gets shipped to production. Knowing all of them is not necessary, but if you have a basic understanding of each one, you can decide on the most efficient one for your scenario.
Using a loop is almost a must in our day to day life. But have you ever thought what kind of loop should you use? Do you know the difference between enumerables and iterables? This article sheds some light in this space, so read on if you’re interested.
You’ve spent many hours trying to improve your web performance and have got it to a good speed. What happens next? How do you ensure it remains in good shape especially if you’re working in a team with diverse backgrounds and level of coding.
I was working on a project a week ago and had a local branch (with a few commits) I was going to push to upstream to create a PR (pull request). However, after pulling down master and rebasing, I realised all of my code except my first commit is gone after rebase 😱.
There are many situations where we want to see what’s wrong with out code without the trouble of changing source code and push the changes again, regardless of whether we’re using local environment or production. Most folks start by writing
console.log statements throughout their code base and go step by step to find the place where the bug is happening. That’s OK for beginners and where you have access to source code, but what if you don’t want to waste so much time or you don’t even have access to source code?
There are many situations where we’d like to see our web page in fullscreen mode. Be it games, online courses, video tutorials, or simply wanting more reading space while reading a book. What we usually do in these sort of scenarios is we manually set our browser’s tab/window in fullscreen mode (F11), but the result is not always what we expect, because some content is not designed to be viewed in fullscreen mode. Besides, what if we help our users to go fullscreen automatically instead, again it all comes to having a better user experience.
