It has everything a developer needs to start coding. Auto-completion feature, using linting tools are good but best is debugging made simpler for me.

The best thing which makes it most valuable is its auto correction and intelligent auto fill or suggestions which makes this ide most useful and prominent in the developers.The number of coding language supported are more than 50!

The thing I liked about CodeRunner is it is a lightweight, programming text editor that supports multiple programming languages such as python, PHP, etc.
