JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.

Advanced tools
Return a regular expression to capture a function name.
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!
Regular expression to capture a function name.
npm install @stdlib/regexp-function-name
var reFunctionName = require( '@stdlib/regexp-function-name' );
Returns a regular expression to capture a function
name.
function beep() {
return 'boop';
}
var RE_FUNCTION_NAME = reFunctionName();
var str = RE_FUNCTION_NAME.exec( beep.toString() )[ 1 ];
// returns 'beep'
Regular expression to capture a function
name.
var str = reFunctionName.REGEXP.exec( Math.sqrt.toString() )[ 1 ];
// returns 'sqrt'
var Int8Array = require( '@stdlib/array-int8' );
var reFunctionName = require( '@stdlib/regexp-function-name' );
var RE_FUNCTION_NAME = reFunctionName();
function fname( fcn ) {
return RE_FUNCTION_NAME.exec( fcn.toString() )[ 1 ];
}
var f = fname( Math.sqrt );
// returns 'sqrt'
f = fname( Int8Array );
// returns 'Int8Array'
f = fname( Object.prototype.toString );
// returns 'toString'
f = fname( function () {} );
// returns ''
