#Underscore.Excerpt

Smarter select queries from Underscore.js collections.

var kitties = _.excerpt(felids, {
	species: 'cat',
	aggressive: { operator: '==', value: false }, // Has not remarks
	ageInDays: { operator: '<', value: 50 }
});

Usage

Underscore.Excerpt plugin extends filter method by custom operators. By default filter hash consists of primitive values, but if you want to get some flexibility, set an object with a comparative operator and argument value fields.

Available operators:

• < for lower than
• > for greater than
• <= for lower than or equivalent
• >= for greater than or equivalent
• == for non-strict comparison (e.g. '' == false)
• != for non-strict not equivalent
• regexp for test a value with a regular expression
