+ + + + + +
+ +## Usage + +```javascript +var someOwnBy = require( '@stdlib/object/some-own-by' ); +``` + +#### someOwnBy( obj, n, predicate\[, thisArg ] ) + +Tests whether an `object` contains at least `n` own properties which pass a test implemented by a `predicate` function. + +```javascript +function isNegative( value ) { + return ( value < 0 ); +} + +var obj = { + 'a': 1, + 'b': -2, + 'c': 3, + 'd': -1 +}; + +var bool = someOwnBy( obj, 2, isNegative ); +// returns true +``` + +Once the function finds `n` successful properties, the function **immediately** returns `true`. + +```javascript +function isPositive( value ) { + if ( value < 0 ) { + throw new Error( 'should never reach this line' ); + } + return ( value > 0 ); +} + +var obj = { + 'a': 1, + 'b': 2, + 'c': -3, + 'd': 4 +}; + +var bool = someOwnBy( obj, 2, isPositive ); +// returns true +``` + +The invoked `function` is provided three arguments: + +- **value**: object property value. +- **key**: object property key. +- **obj**: input object. + +To set the function execution context, provide a `thisArg`. + +```javascript +function sum( value ) { + this.sum += value; + this.count += 1; + return ( value < 0 ); +} + +var obj = { + 'a': 1, + 'b': 2, + 'c': 3, + 'd': -5 +}; + +var context = { + 'sum': 0, + 'count': 0 +}; + +var bool = someOwnBy( obj, 1, sum, context ); +// returns true + +var mean = context.sum / context.count; +// returns 0.25 +``` + +
+ + + + + +
+ +## Notes + +- An [`Object`][mdn-object] refers to a JavaScript object, which is a collection of properties. Each property is an association between a key (or name) and a value. The key can be a string or a symbol, and the value can be any JavaScript value, including functions and other objects + +- If provided an empty `object`, the function returns `false`. + + ```javascript + function alwaysTrue() { + return true; + } + var bool = someOwnBy( {}, 1, alwaysTrue ); + // returns false + ``` + +- The function does **not** skip `undefined` elements. + + + + ```javascript + function log( value, key ) { + console.log( '%s: %s', key, value ); + return ( value < 0 ); + } + + var obj = { + 'a': 1, + 'b': void 0, + 'c': void 0, + 'd': 4, + 'e': -1 + }; + + var bool = someOwnBy( obj, 1, log ); + /* => + a: 1 + b: void 0 + c: void 0 + d: 4 + e: -1 + */ + ``` + +- The function provides limited support for dynamic objects (i.e., objects whose `length` changes during execution). + +
+ + + + + +
+ +## Examples + + + +```javascript +var randu = require( '@stdlib/random/base/randu' ); +var someOwnBy = require( '@stdlib/object/some-own-by' ); + +function threshold( value ) { + return ( value > 0.95 ); +} + +var bool; +var obj = {}; +var i; + +for ( i = 0; i < 100; i++ ) { + obj[ 'key'+i ] = randu(); +} + +bool = someOwnBy( obj, 5, threshold ); +// returns +``` + +

- -## Notes - -- An [`Object`][mdn-object] refers to a JavaScript object, which is a collection of properties. Each property is an association between a key (or name) and a value. The key can be a string or a symbol, and the value can be any JavaScript value, including functions and other objects - -- If provided an empty `object`, the function returns `false`. - - ```javascript - function alwaysTrue() { - return true; - } - var bool = someOwnBy( {}, 1, alwaysTrue ); - // returns false - ``` - -- The function does **not** skip `undefined` elements. - - - - ```javascript - function log( value, key ) { - console.log( '%s: %s', key, value ); - return ( value < 0 ); - } - - var obj = { - 'a': 1, - 'b': void 0, - 'c': void 0, - 'd': 4, - 'e': -1 - }; - - var bool = someOwnBy( obj, 1, log ); - /* => - a: 1 - b: void 0 - c: void 0 - d: 4 - e: -1 - */ - ``` - -- The function provides limited support for dynamic objects (i.e., objects whose `length` changes during execution). - -
