Ionic 7 framework is here!

Ionic 7 is the latest and greatest version of the popular mobile app development framework. It’s so good, it’ll make you want to put on your favorite coding socks and dance around your computer like nobody’s watching.

But in all seriousness, Ionic 7 offers some fantastic benefits over its older versions. Its improved performance will have your app running like a well-oiled machine, or at least like a machine that’s had a few cups of coffee in the morning. And with the updated design system, your app will look so good it’ll make your users wonder why they ever bothered with other apps in the first place.

And let’s not forget Capacitor 3, the native runtime that allows developers to build cross-platform mobile apps using web technologies. It’s like having a magical wand that can turn your web app into a mobile app with just a few flicks of your wrist.

But upgrading to Ionic 7 isn’t just a walk in the park, it’s more like a marathon. You’ll need to update your dependencies, configuration files, and code. It’s enough to make a developer break out in a cold sweat, or at least reach for the coffee (or energy drink) to power through.

But fear not, intrepid developer! Once you’ve upgraded and tested your app, you can sit back and relax knowing that you’ve done your part to keep up with the latest and greatest in mobile app development. And who knows, maybe your app will become the next big thing and you’ll be able to retire to a tropical island with nothing but your laptop and a good book (or maybe just a good IDE).

So what are you waiting for? Upgrade to Ionic 7 and start building mobile apps that will make your users say “Wow, this app is so great I want to give the developers a hug… or at least a virtual high-five.”

How to Implement Binary Search in JavaScript


function binarySearch (list, value) {
  // initial values for start, middle and end
  let start = 0
  let stop = list.length - 1
  let middle = Math.floor((start + stop) / 2)

  // While the middle is not what we're looking for and the list does not have a single item
  while (list[middle] !== value && start < stop) {
    if (value < list[middle]) {
      stop = middle - 1
    } else {
      start = middle + 1
    }

    // recalculate middle on every iteration
    middle = Math.floor((start + stop) / 2)
  }

  // if the current middle item is what we're looking for return it's index, else return -1
  return (list[middle] !== value) ? -1 : middle
}

const list = [2, 5, 8, 9, 13, 45, 67, 99]
console.log(binarySearch(list, 99)) // 7 -> returns the index of the item

JS Infinite Alert Prank Code gets Japanese Girl in Serious Trouble

Ars Technica Reporting:

Explaining her actions, the girl said that she’d run into such pranks herself and thought it would be funny if someone clicked the link.

The Twitter user referenced in the message, 0_Infinity_, has a protected account, but the user left a message in their bio field suggesting that they don’t understand why there’s so much fuss about the script today, as it was written in 2014.

To protest the actions of the Japanese police and the absurdity of calling this act a crime, Tokyo developer Kimikazu Kato has published on GitHub a project called Let’s Get Arrested. Forking the project and then creating a branch named gh-pages will create a simple GitHub-hosted website that contains nothing but the infinitely looped alert, putting criminality at our fingertips.

for ( ; ; ) {
    window.alert("　∧_∧　ババババ\n（ ・ω・)=つ≡つ\n（っ ≡つ=つ\n`/　　)\n(ノΠＵ\n何回閉じても無駄ですよ～ww\nm9（＾Д＾）プギャー！！\n　byソル (@0_Infinity_)")
}

Calling her a criminal is totally absurd.

How to Format Post Dates to show Time since Post

Ever wonder how to format your post times to show up like Twitter or Facebook time since post in minutes, hours, etc? Here is an example of a facebook post 5 hrs ago:

hours ago

I recently had to do this for one of my Ionic mobile apps. Here is the function in JavaScript:

function formatTimeSincePost(time) { // SHOW TIME SINCE POST

    var now = new Date();
    var postTime = new Date(Date.parse(time));
    postTime = now.getTime() – postTime.getTime();

    var timeAgo = Math.ceil(postTime/1000/60);
    var displayTime = "" ;

    if ( timeAgo > 1440 ){ // SHOW DAYS
        displayTime = "" + Math.ceil(timeAgo/60/24) + " days" ;
    }
    else if (timeAgo > 59){ // SHOW HOURS
        displayTime = "" + Math.ceil(timeAgo/60) + " hrs" ;
    }
    else { // SHOW MINUTES
        displayTime = timeAgo + " min" ;
    } 

  return displayTime;
}

You can also add months and years easily if you wish. There you go, happy coding.
