Questions tagged [hashbang]

The hash-bang "#!" is used in AJAX-based web applications to indicate that it has web crawler support. For the shell script shebang ("#!" at the start of a file), use the [shebang] tag instead.

"Hash-bang" is a nickname for the sequence "#!" (octothorpe, exclamation mark). It is used

  • in URLs to indicate that this is a AJAX-based web application with web crawler support

  • in Unix shell scripts to identify the executable that should be used to parse this file, e.g.

    #!/bin/bash
#!/usr/bin/perl -w

    to run a script with the bash shell or with Perl (in warnings mode) respectively. Use the tag for these questions instead.

The way I see it, it seems like hashbangs were a 'hacky' fix that actually do quite well! However, it seems like the History API (pushstate popstate) is the RIGHT way to make a single page application and is actually reasonable now that History.js…
