A Javascript function returns one and only one value. 1 2 3 4 5 6 function sum(x, y) { return 3 + 39; } let life = sum(3, 39); console.log(life); // 42 I bet you already knew that not returning a value from a function, would return ‘undefined’.

AND (&&), Not (!), OR (||) are logical operators in Javascript. You will see that they are the only operators that make up for the entirety of one’s life experiences. Logical operators evaluate two values or expressions, and provide a true or false result. Let us see some examples to know the rules of the game.

Equals (==), not equals (!=), greater than (>), lesser than (<) - Javascript comparison operators cannot get more simple. Let’s dissect these operators a bit. Comparison operators are the ones that you use to.. well, compare. For example: 1 2 3 4 5 6 7 let numCoffee = 3; if (numCoffee < 2) console.

Know how you can use a Javascript object and its props. Javascript objects have properties or props. As you would have seen in the post about objects and primitives, object operations are quite easy. Though objects can mean more than a few things in Javascript, we will limit discussion of an object to the ** real real ** object.

Get to know all the practical knowledge about Javascript primitives and objects. In JavaScript, objects are king. If you understand objects, you understand JavaScript. - W3 Schools Everything except primitives is an object in Javascript. A couple of days back, we were talking about Javascript having the following primitives: bool, number, string, undefined and null.

Don’t know how to type? Get a typewriter. I always wanted to say that. But, if indeed you don’t know types - you can always head over to Javascript types to know more**. So, you know there are types. And, you also know that there can be many a problem in the lousy world of loose typing.

This one thing I never said ever - “once you type, you cannot un-type”. Yep, I make up words and compete on how to level up in my eating my own words. Even if I allegedly uttered those words (which are totally unoriginal anyway), I happily don’t abide by them. I continue to use Javascript without types with all fervour (and have had a stint with typeless / loosely-typed scripting languages).

In a previous post, we saw the power of bindings in Vue. v-model is a powerful way to bind variables and UI rendering in Vue. Let us look at a bit more of v-model in this post. Remind me what is v-model about? In its simplest form.. 1 <input type="text" v-model="myName" label="Your name:"> .

The power of Vue is in making reactive components child’s play. Well, that is true if the child in question is a 8-year old nephew who knows the basics of Javascript - you know what I mean. Consider an example that I have used before - 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 <template> <div class="hello"> <h1>{{ msg }}</h1> <p> <button @click="sayHello">Hello</button> <span v-if="showHello">&nbsp;World!

Oh.. why? Why should we work on theoritical algo problems when we could develop the next Instagram or Salesforce.com? Because, son - you have to learn the different paths to glory. Why take the longer path when it can be shorter? That aside: let us look at multiple ways of reversing a string in Javascript.

Frameworks in Javasripts make your life easy. A Javascript frontend framework encapsulates libraries, code structure, tools and utilities. What a framework contains is left to the philosophy of that framework and the community built around the framework. Javascript world today has numerous frameworks that are company or community maintained. We will delve further in that topic, but first.

I had chosen Laravel as platform to create magic. I came to this decision after painful evaluation of many back-end frameworks to quickly build out applications. Laravel is easy to learn, implement and ship products Many features like auth, ORM are built in and I don’t really need to make my own stupid decisions There is a vast community that seems to know all answers (including the ‘answer to everything’) Of course I don’t know a lot about how to stitch everything together in Laravel, but hopefully my previous PHP experience will help (or not).

I have been on and off Javascript for a long time. It took me till 2018 to get back on track. I am not quite a beginner and no where near an expert, and can write BS till eternity. That makes me the best qualified person to enlighten you about how to ideally learn Javascript.
