Description

You may use the timeout optArg to specify a number of seconds before r.js times out. The default value is 5 seconds.

Example: Concatenate two strings using JavaScript.

r.js("'str1' + 'str2'").run(conn);

Example: Select all documents where the ‘magazines’ field is greater than 5 by running JavaScript on the server.

r.table("marvel").filter(
    r.js('(function (row) { return row.magazines.length > 5; })')
).run(conn);

Example: You may also specify a timeout in seconds (defaults to 5).

r.js("while (true) {}").optArg("timeout", 1.3).run(conn);
