doublescore

doublescore

These are the available utility functions.

close()

Returns a function used to generate callbacks with a service level of max calls and minimum TTL until callback errors

isObject()

Will return TRUE for anything that is typeof object, is not an Array, and is not NULL.

getType()

Will return 'null' for NULL, 'array' for an Array, 'float' for a non-integer number, 'integer' for an integer number, and typeof result for all else.

clone()

Will return a distinct copy of the object it was called from. Date objects are cloned, arrays and objects are recursively cloned down 100 levels max and all else is just passed through.

mixin()

Will return a clone of the original object, with any passed in objects merged in recursively up to 100 levels max. mixin() accepts an arbitrary number of arguments, they will be mixed in from left to right.

timer()

Will return a function that will track time deltas with 1ms resolution and < 0.1% error on average. The returned function accepts a single parameter: reset, which if true will reset the timer, returning the last interval

NOTE: timer() is experimental. 0.5% margin of error for both precision and accuracy at best, probably closer to 1% for most intervals of time. However, deviance is constant regardless of actual time interval measured. Thus, error rates for higher intervals (> 100ms) will be considerably lower than those for short intervals (< 50ms).

Usage

The usage for doublescore is patterned after other utility libraries like underscore.

var __ = require( 'doublescore' );


function do( params, done ) {

	params = __( {
		deep: [
			{
				merge: 'on this default object of'
			}
		],
		strings: {
			objects: 'and',
			numbers: 1.5
		},
		and: null,
		boolean: true,
		etc: [ false, false ],
		from: 'params'
	} ).mixin( params );
	
	//... 
	
	done();

}
