Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.

Test whether at least one element in an array passes a test implemented by a predicate function, while iterating from right to left.
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!
Test whether at least one element in an array passes a test implemented by a predicate function, while iterating from right to left.
npm install @stdlib/array-base-any-by-right
var anyByRight = require( '@stdlib/array-base-any-by-right' );
Tests whether at least one element in an array passes a test implemented by a predicate
function, while iterating from right to left.
function isPositive( value ) {
return ( value > 0 );
}
var x = [ 0, 0, 1, 0 ];
var bool = anyByRight( x, isPositive );
// returns true
If a predicate
function returns a truthy value, the function immediately returns false
.
function isPositive( value ) {
return ( value > 0 );
}
var x = [ -1, -2, -3, -4 ];
var bool = anyByRight( x, isPositive );
// returns false
The predicate
function is provided three arguments:
To set the predicate
function execution context, provide a thisArg
.
function predicate( value ) {
this.count += 1;
return ( value > 0 );
}
var x = [ -1, -2, 3, -4 ];
var context = {
'count': 0
};
var bool = anyByRight( x, predicate, context );
// returns true
var cnt = context.count;
// returns 2
Array.prototype.some
, when performing a linear scan, the function does not skip undefined

.var bernoulli = require( '@stdlib/random-array-bernoulli' );
var isPositiveInteger = require( '@stdlib/assert-is-positive-integer' ).isPrimitive;
var naryFunction = require( '@stdlib/utils-nary-function' );
var anyByRight = require( '@stdlib/array-base-any-by-right' );
var x = bernoulli( 10, 0.1, {
'dtype': 'int8'
} );
// returns <Int8Array>
var out = anyByRight( x, naryFunction( isPositiveInteger, 1 ) );
// returns <boolean>
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.
