Question

How to calculate the run time of a code?

(a) Start time – End time

(b) End time – Start time

(c) Start time/ End time

(d) Start time * End time

I had been asked this question in an interview.

I'm obligated to ask this question of JavaScript Benchmarking and Logging with perfLogger in chapter Parsing, Benchmarking and Logging of JavaScript

Answer 1

Right choice is (b) End time – Start time

The best I can explain: Run-time statements use the static resources created by compile-time statements, but can also create, use, and destroy dynamic resources at run time. The run time of code can be calculated as:

run time = end time – start time
