Node.js - HTTP Module
Which of the following is the correct syntax to parse a query string using the 'querystring' module?
Aquerystring.stringify('name=John&age=30')
Bquerystring.parse('name=John&age=30')
Cquerystring.parse({name:'John', age:30})
Dquerystring.encode('name=John&age=30')
Step-by-Step Solution
Solution:

  1. Step 1: Understand the parse method usage

    The parse method takes a query string like 'name=John&age=30' and converts it into an object.

  2. Step 2: Identify incorrect options

    Stringify converts objects to strings, parse expects a string not an object, and encode is not a method in 'querystring'.

  3. Final Answer:

    querystring.parse('name=John&age=30') -> Option B

  4. Quick Check:

    Parsing syntax = querystring.parse(string) [OK]
Quick Trick: Use parse() to convert query string to object [OK]
Common Mistakes:
  • Using stringify instead of parse
  • Passing object to parse
  • Using non-existent encode method
