In angular, we have a total of 4 type of data binding we have.

Different types of data binding are below.

Two-way data binding

Interpolation :-

We can use double curly braces ( {{}} ) for binding data.
It's provide communication between the component file to html files.

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

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

What is Map() Method? explain with with examples

Hi Guys, In this blog we are going to learn about map() method in JavaScript with detail understanding and examples. Map() :- The map() method is one of the most critical tools in JavaScript programming. Its objective is to apply a function to every element present in an array, resulting in a new collection of effects. The method is highly valued by developers, and in this piece, we will investigate this method, delve into its mechanics, explore its syntax, and provide practical examples. The new array containing results is generated by calling the map() method on an array with a callback function applied to each element. The callback function can be passed as an argument and is executed during the process. For the map() method, the syntax is established as follows: When using the map() method, the the current element being processed, the array that the method was called on, and the index of the current element are passed as arguments to the callback function. It is also possible to u
