Each time you load a web page, those three languages (presented in chronological order) start working, as a result of which the web page receives its final version of UX.
How do APIs help?
- JS has a specially designed mechanism for small scripts
- Compiled JS runs in any browser
- It can be extended for writing larger apps
- JS has a robust testing workflow
- It’s easy to understand and learn for both users and developers
Not the strongest security
If we say the language is easy to learn and understand for users, this means it’s also easily accessible for “bad users” like hackers. JS code is easily viewable to any user, making the web page highly fragile to malicious attacks. Anyone can use the source code without authentication and insert some code into the website.
Rerunning on different platforms
Sometimes it might take slightly more to run
Let’s start with “What is TypeScript and how did it emerge?” first.
Microsoft developed the TypeScript, and it’s continuously improving its features with the capacity of working times faster, supporting ES6 modules, having tools like key and lookup types mapped types, and many more.
For larger-scale projects, you will most probably need the help of TypeScript, so we offer you to:
- explore its complementary TypeScript for more opportunities.
|Doesn’t need to be compiled||Needs to be compiled|
|Better for small size projects||Better for larger projects due to generics & JS features|
|Offers the opportunity to create code without a built step||Most of the npm packages either have a static type definitions or external ones that can be easily installed|
|Doesn’t have a prototyping feature||Has a prototyping feature|
|No need for annotations||There is a need to constantly annotate the code|
|Does not support modules||Supports modules|
|Dynamically typed. The errors are identified during the runtime of the code.||Statically typed. The declared variable does not change its type.|
|Does not have interface or data types||Has interfaces and data types|
TypeScript, in its turn, has disadvantages
- As mentioned above, TypeScript needs to be compiled. That takes additional time and makes the coding process longer.
