1:20 with Andrew Chalkley

A powerful feature of debugging with Chrome is the ability to edit the code being executed on the fly and seeing your experiments without saving any files or restarting servers.

    We found the problem by jumping inside a function and 0:00
    experimented by changing the options in the debug console. 0:03
    But there's another way you can experiment while debugging and 0:07
    that's by editing the code life. 0:11
    If we trigger the break-point again by refreshing the page, 0:13
    on line 42 we can see that the reversed variable 0:17
    is being passed into the local variables that are accessed by the template. 0:20
    This is where we should be passing in the original variable too. 0:26
    I can directly edit the line on 42 to test it out. 0:31
    This doesn't save the file to disk, 0:38
    it's editing the code running in the computer's memory. 0:40
    When we hit Resume, it works. 0:45
    We can temporarily disable the breakpoints with the Deactivate Breakpoints button. 0:50
    And we can test out some other routes. 0:57
    And it works, great. 1:04
    You still have to use your code editor to include your fix there too, and save. 1:07
    I hope you enjoyed seeing some of the debugging tools available to you, and 1:13
    how they can improve your development cycle. 1:17
