What is @stdlib/assert-is-float64array?
The @stdlib/assert-is-float64array npm package is used to check if a value is a Float64Array. This is useful for validating data types in JavaScript, especially when working with numerical computations and ensuring that the data structures are as expected.
What are @stdlib/assert-is-float64array's main functionalities?
Check if a value is a Float64Array
This feature allows you to check if a given value is a Float64Array. The function returns true if the value is a Float64Array and false otherwise.
const isFloat64Array = require('@stdlib/assert-is-float64array');
const arr = new Float64Array(10);
console.log(isFloat64Array(arr)); // true
const notArr = [1, 2, 3];
console.log(isFloat64Array(notArr)); // false
Other packages similar to @stdlib/assert-is-float64array
is-typedarray
The is-typedarray package provides a function to check if a value is a typed array, including Float64Array. It is more general than @stdlib/assert-is-float64array as it can check for various types of typed arrays, not just Float64Array.
typedarray-to-buffer
The typedarray-to-buffer package is used to convert a typed array to a Buffer. While it does not directly check if a value is a Float64Array, it is often used in conjunction with type-checking packages to handle typed arrays in Node.js.
arraybuffer-to-buffer
The arraybuffer-to-buffer package converts ArrayBuffer instances to Buffer instances. Similar to typedarray-to-buffer, it is used in scenarios where handling and validating typed arrays is necessary.
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!
