This\nmodule captures exactly this, with no extra frills.\n\n### Try [a demo](http://begriffs.github.io/decaying-accumulator/)\n\n    // Create an accumulator that decays in one second\n    var DecayingAccumulator = require('DecayingAccumulator'),\n      dac = new DecayingAccumulator({decaySpeed: 1000});\n\n    dac.nudge(1);\n    // now dac.currentValue() === 1\n\n    ...\n\n    // some time later\n    // 0 \u003c= dac.currentValue() \u003c 1\n\nIndividual nudges begin to count for less if they \"bury the needle.\" The\n`currentValue` method always returns within -1 and 1 inclusive. You can\nspecify an initial scale when constructing this class.\n\n    new DecayingAccumulator({decaySpeed: 1000, currentScale: 4});\n    // now currentValue() === 0.25 after nudge(1)\n\nIf nudges have adjusted the scale you can have it reset after a cooldown\nperiod by providing a `cooldownSpeed` argument to the constructor.\n\n## Running tests locally\n\n    npm install\n    node_modules/.bin/mocha\n\n(Or `npm install -g mocha` to add it to your path.)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbegriffs%2Fdecaying-accumulator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbegriffs%2Fdecaying-accumulator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbegriffs%2Fdecaying-accumulator/lists"}
