Learn JavaScript concepts with the Chrome DevTools

Authored by Peter Rybin , Chrome DevTools team

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.

Closures

Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:

webjay

<?php


ignore_user_abort(true);


function syscall ($cmd, $cwd) {
  $descriptorspec = array(
    1 => array('pipe', 'w'), // stdout is a pipe that the child will write to
    2 => array('pipe', 'w') // stderr

# Truly the most ridiculous thing I could think of.

doInstall <- TRUE  # Change to FALSE if you don't want packages installed.
toInstall <- c("XML", "png", "devtools", "RCurl")
if(doInstall){install.packages(toInstall, repos = "http://cran.r-project.org")}
lapply(toInstall, library, character.only = TRUE)

# Some helper functions, lineFinder and makeTable

SCM Post-Commit Message Syntax

To associate an SCM commit with a specific Tracker story, you must include a special syntax in the commit message to indicate one or more story IDs and (optionally) a state change for the story. Your commit message should have square brackets containing a hash mark followed by the story ID. If a story was not already started (it was in the "not started" state), a commit message will automatically start it. For example, if Scotty uses the following message when committing SCM revision 54321:

  [#12345677 #12345678] Diverting power from warp drive to torpedoes.
