JS Picking

Find the JavaScript variables in the midst of chaos

What is JS Picking?

JS Picking is a Chrome extension that helps you find variable paths in your JavaScript application. With value search, you can locate variables based on their values. With change search, you can find variables that change after performing an action. It provides an efficient solution by serializing accessible variables and using a diff algorithm to identify changes.

Summary

Analyze keywords

This addon helps to find variable paths in your JavaScript application. There are 2 ways of doing this:

"Value search"': When you know what value the variable has, you can use this to find how to acces this variable.
"Change search": When you want to find what variables are changed after performing an action.

Second option works by serialising all that is accessible from withing the window object in a big JavaScript string 2 times. Once before a user interaction and once after. A simple diff algorithm is used to see what variables changed. An optional 3th capture can be done to remove noisy variables from the selection that changed without user interaction.
