Top 10 Free Source Code Editors For developers


Web developer work on an application with multiple programming languages, So he writes code or update existing code and uses an editor according to their requirements. So code editor is a very useful tool for a developer. Now let me explain the top 10 free source code editors for developers.

You need a code editor powerful enough to handle anything you can throw at it, whether you are a novice web developer or a veteran code junkie.

This could only be the main part of your toolkit. Since this is a continuous search for most of the field, we wanted to provide some of the best options—free and premium—for you to integrate into your workflow.

What are Free Source Code Editors?

The software that is specifically designed to support developers in coding is code editors or source code editors. These are actually text editors with some additional functionality to handle and edit code. It may be stand-alone or it may be part of the Integrated Development Environment (IDE).

Using the best code editor can improve coding speed. Code editors are specific to the programming language. Some editors support one or two programming languages, while some support multiple programming languages. Suggestions and highlights can only be made based on language support. Code editors do not compile code. It just allows you to write and edit your source code

Difference between text editors and code editors

 A text editor is used to edit text files as the name suggests, and there’s nothing great about it. The notepad is an example of a text editor.

Code editor, on the other hand, is specifically meant to modify the code. They provide you with a variety of features such as auto-indent, bracket matching, variable colors, keywords, comments, preprocessor directives, strings, etc.

Code editors are generally integrated with the IDE (Integrated Development Environment). There are only a few standalone code editors like Notepad++.

The code editor is a tiny piece of software like a text editor. The only difference is that the code editor has more special features than the text editor.

The special function of code editors

Depending on the language used to write, the code editor highlights special keywords, gives recommendations for a certain extent, offers automatic indentation functionality, and also has an integrated terminal as well. Ex: Sublime Text, Visual Studio Code

Structure Editor is a form of the coding editor, or we may claim that it is a functionality that is included in the editors. Structure editing is used to modify the structure of a code based on a syntax tree. The syntax tree is nothing but the structure of the code that is written in the programming language.

Of course, the code editor will do anything (search, replace, maybe with regexes, macros/automation, etc.). And more than that. It is predictably designed to edit the source code (programs, textual data like JSON or XML, etc.), Sometimes it offers syntax highlighting, code snippets, autocompletion, Perhaps basic error detection (like unclosed string), more advanced navigation (jump to matching brace/bracket/parenthesis/tag), maybe auto-indentation, etc

 How do code editors help programmers?

It lets you handle indentation more quickly and also provides auto-formatting so you don’t even have to apply indents yourself most of the time.

It formats the text as you want it, and it also provides syntax highlighting that makes it easier to read the code.

Editors will provide auto-fill so that you don’t have to type a long variable, function, or class name over and over.

It will also automatically close brackets, quotations, parentheses, and other symbols that have an open and closed side.

It can also automatically add import statements as needed, which would otherwise be a real pain and is typically difficult for new programmers to find out.

Editors can provide information about arguments and return types for methods, so you don’t have to look at them every time you use a method that you don’t know about.

It can check for errors as you type, saving tons of time that you would otherwise need to spend on compiler debugging or running time errors.

It can also provide useful tools to update things automatically when you change the name of a variable or class or the location of a class file.
