Java Script Arrow Function ( ES 6 )

Hey Guys, in this blog we are going to learn about What is Java Script Arrow Functions and how we can use it.

Let's get started...

- Arrow function has been introduced in the ES 6.

- Arrow function allow us to write function shortly and simply.

Arrow function looks like below

const funcName = (arg1, arg2, arg3, ..., argN) => expression

- Basically above expression means is it creates a function with name: funcName with the arg1, arg2, ar3,...,argN and after that, it's evaluate the expression and return the results.

- Let's take a simple example let's print the sum of two number using arrow function.
In this example as you can see here function name is sums and it's take two arguments x and y and it's evaluate expression ( x+ y ) and based on evaluation it will return result so here it will return result 25.

- Suppose if in any example if we have only one parameter so in that case we can omitted parentheses from parameters like below example.

- Suppose if you don't have any parameters then we can't remove parentheses. It should be empty like below.

- Suppose if you want to perform some operation within the function then we can also create multi-line arrow function like below.

Different between ``===`` and ``==`` operators in JavaScript

Hello Guys, In this blog we are going to learn about "===" and "==" different with details understanding and examples. JavaScript operators that you might have stumbled upon as a developer include "===", "==". JavaScript's "==" operator is commonly utilized for loose comparison purposes. It functions by converting both of the values to a common type and then comparing them for equality. Here's an example: The comparison operator "==" transforms the value of "17" from a string to a number before determining if the values match. Consequently, if both versions of the data share the same properties and values, the comparison is marked as valid and returns true. The results of the "==" operator can occasionally be surprising, including: The comparison returns true when the "==" operator converts the empty string to the number 0 and compares it to the number 0. This can result in bugs, so ...

Configure and Build Angular application for different environments like QA and Staging

Generally in the angular application by default, we have two environment 1) Development 2) Production Environment. But In some cases, we need to add other environments for our application like QA and staging environment. So let's see how we can add multiple environments in angular application for that we have to perform some steps. Step 1:- Custom Environment File - Here For every target environment, we have to create a new file under the environment folder here i have created two files evnironment.qa.ts and environment.staging.ts Step 2:- Custom Environment Setting - Here now you have to configure your environment name and new environment API URL and other settings For Example:- Step 3:- Need to Update the angular.json file - Now in the angular project you can find the angular.json file. in that file, you have to configure your new environment like below Here I have configure for QA environment St...

What is Pipes in Angular? Built in Pipes with examples and how we can create custom pipe using angular

Hello Guys, In this blog you're going to learn about Angular Pipes with in-built pipes and and customized pipes with details understanding. As an Angular developer, you often come across situations where you need to transform data before displaying it to the user. For instance, you might want to format a date, display a currency in a specific format, or filter a list of items based on some criteria. This is where Angular Pipes come into the picture. Angular Pipes are built-in features that allow you to transform data easily and efficiently. What are Angular Pipes? Angular Pipes are a built-in feature in Angular that allow you to transform data in the template. A pipe takes in a value or values and returns a transformed value. The transformed value is then displayed in the template. Angular Pipes are similar to filters in AngularJS. However, they are more powerful and flexible. Angular Pipes can transform data in a variety of ways, including formatting, filtering, sorting, and more....
