About stdlib...
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!
Return a string representing the source code of a provided function.
npm install @stdlib/function-to-stringAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (see README).
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
var function2string = require( '@stdlib/function-to-string' );Returns a string representing the source code of a provided function.
function add( x, y ) {
return x + y;
}
var str = function2string( add );
// e.g., returns 'function add( x, y ) {\n return x + y;\n}'-
If called on built-in functions, functions created by
Function.prototype.bind(), or other non-JavaScript functions, the function returns a "native" function string similar to the following:"function foo() { [native code] }"For intrinsic object methods and functions,
foois the initial name of the function. -
If called on a function created by the
Functionconstructor, the function returns the source code of a synthesized function declaration having the name "anonymous" and using the provided parameters and function body. -
Starting in ES2018, the ECMAScript specification requires that the returned string contain the exact same source code as it was declared, including any whitespace and/or comments. If the host is unable to access the source code, the specification requires that the returned string be the native function string.
var ndarray = require( '@stdlib/ndarray-ctor' );
var erf = require( '@stdlib/math-base-special-erf' );

var randu = require( '@stdlib/random-base-randu' );
var format = require( '@stdlib/string-format' );
var function2string = require( '@stdlib/function-to-string' );

}-
@stdlib/function-ctor: function constructor.
This package is part of stdlib, 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.
