To use in Observable,

rekey=require('https://cdn.jsdelivr.net/gh/stdlib-js/array-base-rekey@umd/browser.js')

To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:

varrekey=require('path/to/vendor/umd/array-base-rekey/index.js')

To include the bundle in a webpage,

<scripttype="text/javascript"src="https://cdn.jsdelivr.net/gh/stdlib-js/array-base-rekey@umd/browser.js"></script>

If no recognized module system is present, access bundle contents via the global scope:

<scripttype="text/javascript">(function(){window.rekey;})();</script>

Copies and renames specified keys for every element in a provided array.

varx=[{'x':1,'y':2},{'x':3,'y':4}];varmapping={'x':'a','y':'b'};varout=rekey(x,mapping);// returns [ { 'a': 1, 'b': 2 }, { 'a': 3, 'b': 4 } ]

The function has the following parameters:

• arr: input array.
• mapping: object mapping existing keys to new key names.

• The functiononly copies and renames those keys which are present in a provided mapping object. Any keys which arenot present in the provided mapping object, but are present in the original objects, areomitted during object creation.
• The function assumes that each object has the keys specified in a provided mapping object.
• The function performsshallow copies of key values.

This package is part ofstdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
