Why firefox is written in C and javascript UI

0 votes
So, I'm studying Java now, and I'm wondering if it will result in a visible performance boost.

And if many developers utilize a similar technique for windows development (C++ back end and Java UI) or if other languages such as Python are used?

*instead of writing the entire software in another language, use C++ for the back end and other languages for the UI.

First off, Java and JavaScript are entirely separate and dissimilar languages. Firefox doesn't utilize Java at all; it only uses

JavaScript.

Second, this wasn't done to improve speed; rather, it was done to make it easier to create extensions and add-ons for usage with Firefox across all platforms. Code written in C++ must be compiled; once compiled, it can only be used on the

the platform for which it was created.

Since JavaScript is an interpreted language that runs in a browser interpreter, the same extensions may often be used with MacOS, Linux, or Windows (or anything else that Firefox runs on).

And indeed, some applications employ scripting languages for this kind of function (to allow easy customization and extension). For instance, Civilization IV's UI and game logic are totally written in Python and XML due to this, but the graphics code, which is performance-intensive, is still in C++.

How to get current formatted date dd/mm/yyyy in Javascript and append it to an input

The stringent equality operator (===) works exactly like the abstract equality operator (==), with the exception that no type conversion is performed, and the types must be the same to be regarded equal. Javascript Tutorial on Comparison Operators After performing any required type transformations, the == operator will check for equality.  Because the === operator does not perform the conversion, it will simply return false if two values are not of the same type.  Both are equally fast.
