Return true when a proposed time slot overlaps an existing slot. Time ranges use half-open intervals: an event ending at 10:00 does not conflict with one starting at 10:00.
Write down the input contract and the failure cases before coding.
tests
RUNTIME OUTPUT
Ready to run the file open above against 2 tests.
Runs the open file in a restricted browser worker
LEARN FROM THE SOLUTION
Why the solution works.
Two half-open intervals overlap exactly when each starts before the other ends. The strict comparisons make touching boundaries safe, which prevents back-to-back appointments from being incorrectly marked as conflicts.
What this exercise teaches
Intervals
Array predicates
Boundary conditions
A PRACTICAL PLAN
Work through Detect conflicting calendar slots with intent.
Translate the contract.Turn the requirements into a short checklist before editing your-solution.js.
Use the example as evidence.Predict the result for the supplied input, then add one boundary case such as an empty value, a limit, or unexpected input.
Review the implementation.Compare your choices against solution.js only after a real attempt.
EXERCISE FAQ
Before you move on.
What does “Detect conflicting calendar slots” teach?
This advanced JavaScript exercise focuses on Intervals, Array predicates, Boundary conditions. Its requirements define the exact behavior to implement before you write code.
How should I validate this JavaScript solution?
Start with the displayed example input and expected output, then test a boundary case suggested by the requirements. Open your-solution.js and select Run code. The browser executes that file in an isolated worker against the visible test cases.
When should I open the reference solution?
Attempt Detect conflicting calendar slots first. Then open the read-only solution file to compare the contract, edge-case handling, and implementation choices—not simply to copy the final code.
