About stdlib...
</summary>
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
fromCodePoint
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
Create a string from a sequence of Unicode [code points][code-point].
bash
npm install @stdlib/string-from-code-point
javascript
var fromCodePoint = require( '@stdlib/string-from-code-point' );
#### fromCodePoint( pt1[, pt2[, pt3[, ...]]] )
Creates a string from a sequence of Unicode [code points][code-point].
javascript
var out = fromCodePoint( 9731 );
// returns '☃'
In addition to providing [code points][code-point] as separate arguments, the function supports providing an array-like object as a single argument containing a sequence of [code points][code-point].
javascript
var Uint16Array = require( '@stdlib/array-uint16' );
var out = fromCodePoint( 97, 98, 99 );
// returns 'abc'
out = fromCodePoint( new Uint16Array( [ 97, 98, 99 ] ) );
// returns 'abc'
String.fromCharCode][mdn-string-fromcharcode] in the following ways:
- The function provides support for all valid Unicode values (up to 21 bits). While most common Unicode values can be represented using one 16-bit unit, higher code point characters require two 16-bit units (a surrogate pair consisting of a high and a low surrogate) to form a single character. [String.fromCharCode][mdn-string-fromcharcode] does not support surrogate pairs, supporting only UCS-2, a subset of [UTF-16][utf-16].
- This function differs from [String.fromCodePoint][mdn-string-fromcodepoint] in the following ways:
- The function supports explicitly providing an array-like object containing a sequence of [code points][code-point].
- The function requires at least one [code point][code-point].
- The function requires that all [code points][code-point] be nonnegative integers. The function does not support values, such as null, undefined, true, false, '0', '1', etc., which can be cast to integer values.
javascript
var randu = require( '@stdlib/random-base-randu' );
var floor = require( '@stdlib/math-base-special-floor' );
var UNICODE_MAX_BMP = require( '@stdlib/constants-unicode-max-bmp' );
var fromCodePoint = require( '@stdlib/string-from-code-point' );
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = floor( randu()*UNICODE_MAX_BMP );
console.log( '%d => %s', x, fromCodePoint( x ) );
}
@stdlib/string-from-code-point-cli][@stdlib/string-from-code-point-cli]: CLI package for use as a command-line utility.
- [@stdlib/string-code-point-at][@stdlib/string/code-point-at]: return a Unicode code point from a string at a specified position.
