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 ...

Learn About Call(), Apply() and Bind() Method in JavaScript

Hello Guys, In this blog your going to learn about CALL(), APPLY() and BIND() method in JavaScript with details understanding and examples. Invoking a function with a specific this value is possible in JavaScript through call(), apply(), and bind(). These three methods may be comparable in terms of their function, but the way they operate and handle arguments set them apart. call(), apply(), and bind() can be confusing to differentiate, so let's look at how each one differs from one another. Call() :- Method used to invoke a function with specified this value and given arguments - call(). First argument is this value, followed by any expected arguments. For instance, a case in point: Calling findNames() in this scenario, we set the this value to person, thus causing person.name to equate to this.name within the function. APPLY() :- Ahead of time, it's sometimes unclear how many arguments will be required when calling a function. In such instances, the apply() metho...
