Safe Data Parser

Build a data parser utility that safely processes different data formats without throwing exceptions.

Capabilities

Parse JSON strings

  • Parsing valid JSON string '{"name":"Alice","age":30}' returns the parsed object {name: "Alice", age: 30} @test
  • Parsing invalid JSON string '{bad json}' returns an error object @test
  • Parsing empty string '' returns an error object @test

Parse integers from strings

  • Parsing valid integer string '42' returns the number 42 @test
  • Parsing invalid integer string 'abc' returns NaN @test

Execute string operations safely

  • Executing string method toUpperCase on string 'hello' returns 'HELLO' @test
  • Executing string method toUpperCase on null value returns an error object @test
