Widget Tester offers us an ideal test bench to perform JavaScript code tests. The code can be entered manually through a multiline text area, specially designed for this purpose, or by dragging a text string or file to the JS button. We can also enter simple commands through the command line.
In a nutshell, Widget Tester is also a widget that will be used to execute or evaluate the code we indicate, and display its results in the debug or debug window. So we can examine global variables, execute functions and expressions.
You can free download Widget Tester 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
