Array Method Chain Visualizer
Apply a safe list of array operations to numeric JSON and inspect the complete result after every step in your browser.
Local only. Up to 1,000 finite numbers (absolute value ≤1,000,000,000), 20,000 input characters and 20 operations (500 characters). Operations: filter-even, filter-odd, dedupe, sort-asc, sort-desc, reverse, take N, drop N (N = 0–1,000). No JavaScript expressions.
