How does lodash.isTypedArray work?
In the Lodash library, lodash.isTypedArray is a function that takes a value as input and returns a boolean indicating whether the value is a typed array or not. A typed array is a type of array in JavaScript that is optimized for storing a specific type of data, such as integers or floating-point numbers. Typed arrays have a fixed length and are stored in contiguous memory, which makes them more efficient to work with than regular JavaScript arrays for certain types of operations. The lodash.isTypedArray function checks if the input value is an instance of one of the six typed array types defined in the ECMAScript specification: Int8Array, Uint8Array, Uint8ClampedArray, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array, and BigInt64Array, or if it is an instance of any of their subclasses. Here's an example implementation of lodash.isTypedArray that demonstrates how the function works: javascript Copy code {{{{{{{ const _ = require('lodash'); console.log(_.isTypedArray(new Int8Array())); // true console.log(_.isTypedArray([])); // false In this example, we first import the lodash library. We then call _.isTypedArray(new Int8Array()) to check if the input value is a typed array instance of Int8Array. The function returns true because new Int8Array() is a typed array. We then call _.isTypedArray([]) to check if an empty array is a typed array. The function returns false because [] is not a typed array. Overall, lodash.isTypedArray provides a simple and convenient way to check if a value is a typed array in JavaScript.
Ai Example
1 2 3 4 5 6 7const _ = require("lodash"); console.log(_.isTypedArray(new Int8Array())); // true console.log(_.isTypedArray(new Float64Array([1, 2, 3]))); // true console.log(_.isTypedArray([])); // false console.log(_.isTypedArray({})); // false console.log(_.isTypedArray("hello")); // false
In this example, we first import the lodash library. We then call _.isTypedArray with several input values to check if they are typed arrays. The first two calls to _.isTypedArray check if the input values are instances of typed arrays (Int8Array and Float64Array). The function returns true for both of these inputs because they are typed arrays. The next three calls to _.isTypedArray check if the input values are not typed arrays. In each case, the function returns false because the input value is not a typed array. Overall, lodash.isTypedArray is a simple and useful utility for checking if an input value is a typed array.
