sru

A dead simple, high performance, somewhat-recently-used cache.

O(1) insertion, retrieval and deletion.

Examples

function cubed (x) {
  return x * x * x
}
 
let sru = require('sru')
let cache = sru(100)
 
console.log(cache(8, cubed), 512)
console.log(cache(8, cubed), 512) // cubed was not called this time
