Where

After reading a friend’s article about constraint notation, I realized I need this… for things.

With prior authorization and a promise to give the due props, I sucked this functionality out of Ramda and re-wrote it without any dependencies, here. The pattern of parsing a spec object for later comparison works great in native Array.filter() or in object streams–like when using highland.js.

//obligatory declarations
var where = require( 'where-filter' );
var isComplete = where( {complete: true} );
// ...

tasks.filter( isComplete );

// or this

highland( tasks ).filter( isComplete ).toArray( function ( filtered ) {
  //...
} );
