find maped element of an array that will satisfy condition of some
npm install mapsomeFind maped element of an array that will satisfy condition of some.
[Map][mapURL] + [Some][someURL] + early return of an element;
``
npm i mapsome --save
Lets look at regular map-filter example:
`js
const map = (a) => ++a;
const condition = (a) => a > 2;
[1, 2, 3, 4]
.map(map) / loop full array /
.filter(condition) / loop full array again /
.pop(); / get value /
// returns
3
`
With mapsome this would look this way:
`js
const map = (a) => ++a;
const condition = (a) => a > 2;
mapsome(map, condition, [1, 2, 3, 4]);
// returns
3
`
mapsome works much faster because no need map full array, first satisfied condition will break the loop.
mapsome could be used with map function only:
`js
const map = (a) => ++a;
mapsome(map, [0, 0, 3, 0]);
// returns
3
// same as
mapsome(map, a => a, [0, 0, 3, 0]);
// returns
3
`Environments
In old node.js environments that supports es5 only, mapsome could be used with:
`js`
var mapsome = require('mapsome/legacy');
mapsome could be installed via bower with:
`sh`
bower install mapsome --save
When loaded in browser mapsome uses global variable with same name (when browserify or webpack` did not used).
