I am currently in the process of learning Javascript, so the best way to strengthen my learning is by writing blogs on the topics I learned and sharing them. In today's blog, I have shared about data types in Javascript.

In programming, a variable is a value that can change, depending on conditions or on information passed to the program. The type of a variable can change at any moment because JavaScript is a dynamic and weakly typed language, so you are not required to define it when you declare a variable. The distinctions between these data types are crucial to comprehend since they have an impact on the functionality and behavior of your code. You can write code that is more effective and simpler to maintain by utilizing the right data type for the context.

There are six fundamental data types in JavaScript.

1. Numbers: JavaScript has a single type for numbers, which includes both integers and floating-point values. There is no separate type for representing only integers or only floating-point values.

2. Strings: A string is a sequence of characters, such as "Hello, world!". You can use single or double quotes to define a string in JavaScript, as long as you use the same type of quotes to start and end the string.

3. Booleans: A boolean represents a true or false value. It's often used to control the flow of a program by using conditional statements such as "if" and "else".

4. Null: The null data type represents an intentional absence of a value. It's different from an undefined value, which means that a variable has been declared but has not yet been assigned a value.

5. Undefined: As mentioned above, an undefined value means that a variable has been declared but has not yet been assigned a value.

6. Objects: An object is a collection of key-value pairs. You can use objects to store and manipulate complex data structures, such as arrays and dictionaries.

That's all from my side. Have a great time learning and building!
