Readme
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!
Alias for

global.
npm install @stdlib/utils-eval
var evil = require( '@stdlib/utils-eval' );
Alias for eval

var v = evil( '5*4*3*2*1' );
// returns 120
eval
is treated differently by the compiler. For example, when evaluating code containing block-scoped declarations (e.g., let
, const
, function
, class
), the compiler may throw an error
complaining that block-scoped declarations are not yet supported outside of strict mode
. One possible workaround is to include "use strict";
in the evaluated code, as done in the example below.var evil = require( '@stdlib/utils-eval' );
var ctors;
var fcn;
var i;
function compile( ctor ) {
var name;
var str;
name = ctor.match( /^(\w*)Array$/ )[ 1 ];
name += 'DataArray';
str = '';
str += '(function create(){';
str += '"use strict";';
str += 'class '+name+' extends '+ctor+'{';
str += 'constructor(x){';
str += 'super(x);';
str += '}';
str += '}';
str += 'return '+name+';';
str += '})();';
return str;
}
ctors = [
'Int8Array',
'Uint8Array',
'Uint8ClampedArray',
'Int16Array',
'Uint16Array',
'Int32Array',
'Uint32Array',
'Float32Array',
'Float64Array',
'Array'
];
for ( i = 0; i < ctors.length; i++ ) {
fcn = evil( compile( ctors[i] ) );
console.log( fcn.toString() );
}
@stdlib/utils-eval-cli
: CLI package for use as a command-line utility.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.
