Question

Which of the following reads the textual contents of a URL and returns as a string?

(a) spawn(f);

(b) load(filename,…);

(c) readFile(file);

(d) readUrl(url);

This question was addressed to me at a job interview.

Query is from Remote Logging topic in chapter Parsing, Benchmarking and Logging of JavaScript

Answer 1

The correct choice is (d) readUrl(url);

The best explanation: readUrl() opens an input connection to the given string url, read all its bytes and convert them to a string using the specified character coding or default character coding if an explicit coding argument is not given.
