Compares different approaches to set an object property
Testing different ways to convert JavaScript's URL object to its string representation.
- Array.push - Array.apply: Array.apply(null, Array(100)) - Destructuring operator: [...Array(100)] - Array.prototype.fill Array(100).fill(undefined) - Array.from Array.from({ length: 100 })

Compares performance on the same task using Lodash vs two styles of Ramda vs two styles of "native" Javascript. In all cases the task is pulling "counter" property from each item in an array, filtering out odd items, squaring them, then returning those squared values that have less than two digits. Comparing performance of: Lodash funcional style (idiomatic) vs Lodash funcional style (performance optimized with spread) vs Ramda without relying on currying or composition vs Ramda with currying and composition vs Ramda with transducers vs VanillaJS funcional style (idiomatic) vs VanillaJS funcional style (performance optimized with spread) vs VanillaJS procedural.
