ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
turf-simplify
Advanced tools
Takes a LineString or Polygon and returns a simplified version. Internally uses simplify-js to perform simplification.
Parameters
feature
(Feature<(LineString | Polygon | MultiLineString | MultiPolygon)> | FeatureCollection | GeometryCollection) feature to be simplifiedtolerance
number simplification tolerancehighQuality
boolean whether or not to spend more time to create
a higher-quality simplification with a different algorithmExamples
