Install
$ npm install like-ar
Usage
The function likeAr
wraps an object. The wraped object can be used like an array
with some array functions: forEach
, map
, filter
y join
.
These functions receive a callback in the same way that the array version does.
var likeAr = require('like-ar');
var object={
lastName:'Perez',
firstName:'Diego',
phone:'+45-11-2222-3333'
}
likeAr(object).forEach(function(value, attrName, object){
console.log(attrName,':',value);
});
console.log(
likeAr(object).filter(function(value, attrName){
return attrName.contains('Name');
}).map(function(value,attrName){
return attrName+':'+value
}).join(', ')
);
API
likeAr(object)
The callback functions receive these parameters: value
, key
and the original object.
The functions that in the Array case returns Arrays returns a chainable object.
function | returned value |
---|
forEach(cb, this) | undefined |
map(cb, this) | chainable object with the same keys and the value mapeds |
filter(db, this) | chainable object with the same keys and values for only that key/value that returns true in the callback function |
join(separator) | string with the join of the values |
array() | array of values |
keys() | array of keys |
plain() | plain object without likeAr functions |
likeAr.toPlainObject(array [,keyName [,valueName]])
likeAr.toPlainObject(arrayOfKeys, arrayOfValues)
Returns a plain object from an array of pairs (or a pair of arrays) of key/values.
Default values: 0
and 1
if keyName
is not set. "value"
for valueName
if keyName
is set.
Usage
var likeAr = require('like-ar');
var pairs=[['lastName', 'Perez'], ['firstName', 'Diego']];
console.log(likeAr.toPlainObject(pairs));
var pairs=[{field:'lastName', value:'Perez'}, {field:'firstName', value:'Diego'}];
console.log(likeAr.toPlainObject(pairs, 'field'));
