What this example teaches

Dynamic Programming

Output

The function returns the correct result while keeping time and space tradeoffs visible.

Line-by-line explanation

  • Line 1 sets up the Dynamic Programming example: function uniqueValues(values) {.
  • Line 2 adds one required part of the working pattern: const seen = new Set();.
  • Line 3 exposes the output so you can verify the behavior: return values.filter((value) => {.
  • Line 4 adds the decision or filter that controls the result: if (seen.has(value)) return false;.
  • Line 5 adds one required part of the working pattern: seen.add(value);.
  • Line 6 exposes the output so you can verify the behavior: return true;.

Why this example is useful

This example is useful because it isolates dynamic programming without surrounding noise, so you can see the idea clearly.

Where it is used in real projects

Dynamic Programming appears in real DSA work when a feature needs a clear pattern that can be reviewed and changed safely.

Beginner variation

Change one label, value or condition in the Dynamic Programming example and run it again.

Advanced variation

Combine Dynamic Programming with validation, error handling or reusable structure.
