Tooltips are omnipresent, or rather have to be. While there have been excellent standardisation of user experience since we saw what Bootstrap was capable of, there are days and applications that can throw off users with strange icons, buttons and navigation. Ergo, tooltips. The humble tooltip can provide helpful hints, short messages and guide user on what a particular button, text box or any other element will do before clicking the thingy and causing destruction of a planet.

Multiple Ways to Define Functions in Javascript

We have looked at functions quite a bit on this blog over the last two years. We have seen many avatars of a function including a function object, a function’s method, function of functions, and so on. But, what we have not done is to document all the ways in which we can define functions.

Here’s a quick introduction to Razor pages in ASP.NET core, and an opinionated way to quickly start building applications using Razor pages. And yes, there is a case for using Razor pages even in 2020. So.. ASP.net? Yes, indeed. I have had a love-hate relationship with ASP.NET through years. I am way less productive using ASP.

Reusable debounce function for Vue

Debounce operations in Vue using this 10 line script. Avoid loadash and friends. What is debounce? Delay and throttle operations to wait and collect user input before doing something with the input. The “something” can be updating another field, doing an API call, or starting a timer to self-destruct. Did you not debounce earlier?

Centralized alert for Vuetify

Centralize all error, warning and info alerts in one place. I like v-alert and tend to over-use it. It enables us to show detailed notifications (error or otherwise) - without significantly causing user inconvenience.

A Different IIFE Syntax

Here’s a different syntax for our favourite IIFE’s. Immediately invoked function expressions enable us to write functions without using “functions”. Well - just kidding. They are functions but with a different syntax. A typical IIFE looks like this - 1 2 3 4 5 6 7 8 9 10 11 const x = 1, y = 9; var sum = 0; (function() { sum = x + y; console.

Here’s a shorter, readable way to copy props from one object to another subject to defined conditions. The shortest way to copy object (when you don’t quite care about copying sub objects by reference) - 1 2 3 4 5 const planet = { name: "earth", position: 3 }; const newPlanet = { .
