To use in Observable,

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

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

varput=require('path/to/vendor/umd/array-put/index.js')

To include the bundle in a webpage,

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

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

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

Replaces specified elements of an array with provided values.

varx=[1,2,3,4];varout=put(x,[1,3],[20,40]);// returns [ 1, 20, 3, 40 ]varbool=(out===x);// returns true

The function supports the following parameters:

• x: input array.
• indices: list of indices.
• values: values to set. Whenindices contains one or more elements,values must be broadcastcompatible withindices (i.e., must have either one element or the same number of elements asindices).
• options: function options.

The function supports the following options:

• mode: indexmode. Default:'normalize'.

Ifindices is an empty array, the function returns the input array unchanged.

varx=[1,2,3,4];varout=put(x,[],[20,40]);// returns [ 1, 2, 3, 4 ]

The function supports broadcasting avalues array containing a single element against anindices array containing one or more elements.

varx=[1,2,3,4];varout=put(x,[1,3],[20]);// returns [ 1, 20, 3, 20 ]

By default, the function normalizes negative integer indices to positive integer index equivalents.

varx=[1,2,3,4];varout=put(x,[-3,-1],[20,40]);// returns [ 1, 20, 3, 40 ]

To specify an alternative indexmode, provide amode option.

varx=[1,2,3,4];varout=put(x,[-10,10],[20,40],{'mode':'clamp'});// returns [ 20, 2, 3, 40 ]

• The function mutates the input arrayx.
• Because each index is only validated at the time of replacing a particular element, mutation may occur even when one or more indices are out-of-bounds, including when the indexmode indicates to raise an exception.
• Thevalues array must have adata type which can besafely cast to the input array data type. Floating-point data types (both real and complex) are allowed to downcast to a lower precision data type of thesame kind (e.g., element values from a'float64' values array can be assigned to corresponding elements in a'float32' input array).

• @stdlib/array-mskput:replace elements of an array with provided values according to a provided mask array.
• @stdlib/array-place:replace elements of an array with provided values according to a provided mask array.
• @stdlib/array-take:take elements from an array.

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.
