Should You Learn Python Or Javascript
Why you should learn JavaScript and Python in 2022
A new year brings new opportunities for aspiring developers and people who are trying to leave their non tech role so that they can get hired as a developer. Ane of the most common dilemmas that these people face is figuring out what technical stack to acquire and in what direction they should exist going when information technology comes to learning a new programming language from scratch. There are endless options and many different paths that someone could choose to become downwardly.
Arguably ii of the about popular and talked about programming languages in the world are JavaScript and Python. If you search for JavaScript and Python chore roles on whatsoever job board you are highly likely to come across hundreds if not thousands of results. The market is and always will be hot for these two highly sought later on languages and that is not going to modify anytime soon. Both languages share quite a few similarities besides. They are both C based languages which substantially means that they are general purpose, procedural and accept lexical scopes among other things.
Dynamic vs Static
Ane of the biggest standout points is the fact that JavaScript and Python are dynamically typed languages. In a manner of sense a dynamically typed programming language does non require variables to be explicitly declared prior to their usage. And in the reverse a statically typed programming language prevents variables from getting reassigned to a different type. All of this will become more clear in the examples below.
Java Case
String myName ; // Variable with a type of string myName = "Tony Stark" ; // The cord is chosen Tony Stark myName = 24 ; // Reassigning the string into a number
If you were to run this Java code you would go either a compile error or runtime mistake. It is not possible to reassign static types to a different type. You can just use another string similar "Steve Rogers".
JavaScript Case
allow myName ; // Variable that has no type myName = " Tony Stark " ; // The variable has a blazon of string myName = 24 ; // The variable has changed its type dynamically to a number
Now if you were to run this JavaScript code yous would become no errors as information technology is perfectly valid. The variable name is now the number 24.
Python Instance
my_name = "Tony Stark" # The variable has a type of string my_name = 24 # The variable has changed its type dynamically to an int
Similarly if you lot were to run this Python code y'all would also get no errors equally information technology is perfectly valid. The variable name is now the Int 24.
Data Types
Data types are essentially ways to store data within of an application. The type of data type specifies what can be stored and how information technology tin can be managed. Below you volition find a list of some of the data types that each linguistic communication has.
JavaScript Data Types
Text Type: string
Numeric Blazon: number
Boolean Type: boolean
Mapping Type: object
Sequence Type: array
Python Data Types
Text Type: cord
Numeric Type: int, bladder, circuitous
Boolean Blazon: boolean
Mapping Type: dict
Sequence Type: listing, tuple, range
Comparing the syntax
Next we volition compare the syntax for both programming languages then you can see how like shooting fish in a barrel information technology is to transition between the two of them. Outset let me run through a few differences between the languages.
JavaScript
- Uses semicolons
- Uses curly braces for code blocks
- Uses the CamelCase naming convention for variables for example firstName
- Uses
panel.logfor outputting messages to the panel
Functions use this syntax:
function myFunc () { console . log ( ' Hullo World ' ); } const myFunc2 = () => { console . log ( ' Hello Earth 2 ' ); }; myFunc (); myFunc2 ();
Python
- Does non use semicolons
- Does not use curly braces
- Uses the Ophidian Case naming convention for variables for example first_name
- Uses indentation for code blocks
- Uses
printfor outputting messages to the console
Functions use this syntax:
def my_func (): print ( 'Hello Globe' ) my_func ()
Text
Both languages output a string type variable
JavaScript Syntax
permit myName = " Tony Stark " ; console . log ( typeof myName ); // cord
Python Syntax
my_name = "Tony Stark" impress ( type ( my_name )) # str
Numeric
In this case both variables output a number in JavaScript
JavaScript Syntax
let num = 9000 ; let num2 = 9.0 ; panel . log ( typeof num ); // Number console . log ( typeof num2 ); // Number
Python Syntax
In this example Python is able to see the deviation between a number and a float because they are built in data types
num = 9000 num_2 = 9.0 print ( type ( num )) # Int impress ( type ( num_2 )) # Bladder
Boolean
The output is almost exactly the aforementioned the only departure is that JavaScript uses a lowercase "t" for true whereas Python uses an uppercase "T".
JavaScript Syntax
let magician = truthful ; panel . log ( sorcerer ); // boolean
Python Syntax
In this example Python is able to see the difference betwixt a number and a float considering they are built in data types
sorcerer = Truthful print ( wizard ) # bool
Mapping
JavaScript uses the object data construction whereas Python uses the dictionary information structure. From looking at the examples you can encounter that they are very akin. The departure is that JavaScript does not require quotes for the keys whereas Python requires them for the keys in the cardinal value pair.
The keys are on the left for example name and the values are on the right for case Tony Stark.
JavaScript Syntax
const myprofile = { name : ' Tony Stark ' , age : 48 , superhero : ' Iron Homo ' , }; console . log ( myprofile );
Python Syntax
my_profile = { "name" : "Tony Stark" , "age" : 48 , "superhero" : "Fe Human" , }; impress ( my_profile );
Sequence
JavaScript uses an Array which is a type of object data structure whereas Python uses the list data structure. Every bit you tin can see they have many similarities in terms of the syntax you write.
JavaScript Syntax
const myArr = [ one , ii , 3 , 4 , five , 6 , 7 , viii , 9 , x ]; panel . log ( typeof myArr ); // object
Python Syntax
myArr = [ 1 , two , 3 , iv , 5 , 6 , 7 , 8 , 9 , 10 ] print ( type ( myArr )) # list
Where to go from here
There are many platforms you can get to if you desire to learn JavaScript and Python. Personally I recall that freeCodeCamp and Udemy have great courses for both of them. These are the ones that I recommend.
