For a basic understanding let’s see the basic operation/uses of both.
Observe any website, and just try to analyse and observe its components. The main building blocks/ components are built with the help of HTML . And these html components are then enhanced in looks and are made more presentable with the help of CSS. But even after designing and giving eye catchy colours, we do need to provide its main functionalities.
|Dynamically typed||Statically typed|
|Shows error at run-time||Shows error at compile time|
|Ideal to use in projects with less code||Ideal to use in projects with complex and lengthy codes|
|Used in ‘React’ to make user interfaces||Used in ‘Angular’ to make user interfaces|
|Is directly executed||Is first converted to JS file and then executed|
|Supported by mostly all the browsers||Not supported by all the browsers|
|Is a client-side scripting language||Used for both client and server side|
While typescript is statistically typed. Which means that we need to declare the type of a variable.
For example, while declaring a variable ‘x’ to use some numeric value we need to specify the type as ‘numeric’ in typescript while in JS we can directly assign the numeric value to ‘x’. Not only this, if we type cast this variable in future then we can directly (without actually typecasting it via code) do that in JS but we do need to follow a few steps of code to do that in TS. (typecasting is the process of converting the datatype of a variable into some other type).
In JS we are aware of the errors in the code, at run time. To be more descriptive, the time when we implement our code and see the output on the screen/browser. We don’t need to compile it manually, it executes automatically. [Text Wrapping Break]
While typescript tells us about the error at compile time. Hence, we will know about the errors before we implement them. This makes a great difference as this helps in error solving and saves a lot of time.
Both of these languages can be considered similar to one another, but existence of both is important for different purposes.
In order to conclude we can say that both of these languages help us by providing functionality to a web-project at different levels and in different ways. But the main difference is that JS is ideal for working on a small-scale project where the code is within a few hundred lines while typescript is used to design lengthy, tedious and complex code.
