Usage
extend (destination, source, ...)
- @param {Object} destination
- @param {Object} sources ...
- @return {Object} destination extended
For each source, shallow merge its key/values to the destinatino. Sources are read in order, meaning the same key in a later source will overwrite the key's value earlier set.
var extend = ; // sample objectsvar a = hello: 'universe' b = speak: 'loudly' ; // change a;ashoulddeep; // shallow clone to cvar c = ;alanguage = 'en'; ashoulddeep;cshoulddeep;
extend.include (props, ...)
- @param {String} each property to include as an argument
- @return {Function} reusable include function
Create a new object that only includes the properties
specified. Unlike extend()
, the original objects
will not be modified.
This method will return a function that can be
reused for the specified properties. Like extend()
,
this function accepts an unlimited number of objects
as parameters to draw from. Also, the same key in later
specified objects will overwrite earlier specified values.
var extend = include = extend; var a = one: 1 three: 3 b = zero: 0 two: 2 ; var c = ; cshoulddeep;
extend.exclude (props, ...)
- @param {String} each property to exclude as an argument
- @return {Function} reusable exclude function
Create a new object that include all but the properties
specified. Unlike extend()
, the original objects
will not be modified.
This method will return a function that can be
reused for the specified properties. Like extend()
,
this function accepts an unlimited number of objects
as parameters to draw from. Also, the same key in later
specified objects will overwrite earlier specified values.
var extend = exclude = extend; var a = one: 1 three: 3 b = zero: 0 two: 2 ; var c = ; cshoulddeep;
