02
Evaluation Criteria

Comprehensive Model Answer
Verified Solution
It is recommended to avoid creating new objects using new Object(). Instead you can initialize values based on it's type to create the objects.
- Assign {} instead of new Object()
- Assign "" instead of new String()
- Assign 0 instead of new Number()
- Assign false instead of new Boolean()
- Assign [] instead of new Array()
- Assign /()/ instead of new RegExp()
- Assign function (){} instead of new Function()
You can define them as an example,
var v1 = {};
var v2 = "";
var v3 = 0;
var v4 = false;
var v5 = [];
var v6 = /()/;
var v7 = function () {};
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
