array-predicates

js-array-predicates

A set of ultra performant predicates that make working with js arrays easier.

These predicates should handle large quantities of data with ease.

Usage

Using all predicates

var p = require('array-predicates');
someArray.filter(p.byProp('foo'));

Using select predicates

var byProp = require('array-predicates/byProp');
someArray.filter(byProp('foo'));

Available predicates

.byProp(prop)

Matches array items that have the property

someArray.filter(byProp('foo'));

.byPropVal(prop, value)

Matches array items that have a property value loosely matching value.

someArray.filter(byPropVal('foo', 5));
someArray.filter(byPropVal('foo', '5'));// returns the same items as before.

.byPropValue(prop, value)

Matches array items that have a property value exactly matching value.

someArray.filter(byPropValue('foo', 5));
someArray.filter(byPropValue('foo', '5'));// returns different items frome before.

.byVal(value)

Matches array items that loosely match value.

someArray.filter(byVal(5));
someArray.filter(byVal('5'));// returns the same items as before.

.byValue(value)

Matches array items that exactly match value.

someArray.filter(byValue(5));
someArray.filter(byValue('5'));// returns different items frome before.
