Variables: Each programming language has a fundamental need to store data in memory for doing some computations on that data. Now to store and access this data, the memory location needs a name, and this name is called “Variable.” In addition to this, each memory location can store only a specific type of data. And the “DataType” of the variable helps in identifying this.
Loops: Loops are one of the most fundamental concepts available in all programming languages. The loop will execute the set of code repeatedly until the given condition is satisfied. Loop will ask a question; if the given answer is satisfied, then it will perform some actions, again it will ask a question, and this repeats until no further action required. Each time the question is asked, it is called an iteration.
Comments: Comments are one of the basic functionality provided by all the programming languages. Good comments convey essential information to the human reader of the code that the code cannot convey by itself. They make the source code more natural for humans to understand, and compilers and interpreters generally ignore them.
Arrays: The array is one of the most used data structure. Additionally, it stores a collection of similar kinds of objects. Moreover, it helps to organize the data so that values can be easily maintained, searched, and sorted.
In these tutorials, we are concentrating on the intermediate level, more on Arrays inbuilt functions, object, Different inbuilt objects like String, Math.
In these tutorials, we are concentrating on more advanced topics like scheduling, event handlers, error handling, Promises, etc.
