Basic things of Javascript
There are few things, which are the building blocks of your code:
Comments: Comments are human-readable (as opposed to JavaScriptinterpreter- readable) descriptions you can add to your script to make
your script easier to understand and maintain.
Conditionals: Conditionals are logical constructs that you can add to your script to decide whether a particular condition is true or false at
runtime. The most basic conditional is if-else.
Functions: Functions are named groups of statements that you define once, and then reuse to your heart’s content.
Loops: Loops are specialized forms of conditionals. You can add a loop to your script that checks a particular condition multiple times, executing whatever JavaScript code you like, until that condition becomes true or false. Common examples of loops include the for, while, and do-while
loops.
Operators: Operators are the JavaScript answer to conjunctions. Operators include the commas, periods, and other symbols that you use to
compare and assign values to variables.
Variables: Variables are named placeholders that represent the bits of data that you work with in your scripts.
