ArrayBuffer.byteLength Property in JavaScript
ArrayBuffer object in JavaScript represents a fixed-length binary data buffer. The byteLength property of the ArrayBuffer returns an unsigned, 32-bit integer that specifies the size/length of the ArrayBuffer in bytes. Syntax arrayBuffer.byteLength Return Value Returns a number representing the length of the ArrayBuffer in bytes. This value is established when the ArrayBuffer is constructed and cannot be changed. Example: Basic Usage JavaScript ArrayBuffer Example var arrayBuffer = new ArrayBuffer(8); ...
Read MoreAtomics.isLockFree() function in JavaScript
The Atomics object in JavaScript provides atomic operations for use with SharedArrayBuffer objects in multi-threaded environments. The Atomics.isLockFree() method determines whether the JavaScript engine can perform atomic operations on a given byte size without using locks. This method helps optimize performance by checking if atomic operations are lock-free for specific data sizes, which is crucial for high-performance concurrent programming. Syntax Atomics.isLockFree(size) Parameters size: An integer representing the size in bytes. Valid values are typically 1, 2, 4, or 8 bytes corresponding to Int8, Int16, Int32, or BigInt64 array types. Return Value ...
Read MoreArrayBuffer.isView() function in JavaScript
The ArrayBuffer.isView() static method determines whether a given value is an ArrayBuffer view. ArrayBuffer views include typed arrays (like Int32Array, Float64Array) and DataView objects. Syntax ArrayBuffer.isView(value) Parameters value: The value to test whether it's an ArrayBuffer view. Return Value Returns true if the value is an ArrayBuffer view (typed array or DataView), false otherwise. Example 1: Testing Typed Arrays ArrayBuffer.isView() Example // Create typed arrays ...
Read MoreDataView.byteLength property in JavaScript
The byteLength property of the DataView represents the length of the current DataView in bytes. This property is read-only and returns the number of bytes from the start of the DataView to the end. Syntax Its syntax is as follows: dataView.byteLength Parameters This property takes no parameters as it's a read-only property, not a method. Return Value Returns a number representing the length of the DataView in bytes. Example 1: Basic Usage JavaScript Example ...
Read MoreArrayBuffer.slice() function in JavaScript
The ArrayBuffer object in JavaScript represents a fixed-length binary data buffer. The slice() method creates a new ArrayBuffer containing a copy of the specified portion of the original buffer. Syntax arrayBuffer.slice(start, end) Parameters start (optional): The byte index where the slice begins (inclusive). Defaults to 0. end (optional): The byte index where the slice ends (exclusive). Defaults to buffer length. Return Value Returns a new ArrayBuffer containing the copied bytes from the specified range. Example: Basic ArrayBuffer Slicing ArrayBuffer Slice Example ...
Read MoreDataView.byteOffset property in JavaScript
The byteOffset property of the DataView represents the offset (in bytes) from the start of the underlying ArrayBuffer where the DataView begins. Syntax Its syntax is as follows: dataView.byteOffset Return Value Returns a number representing the byte offset of the DataView from the beginning of its ArrayBuffer. Example 1: Basic byteOffset When creating a DataView without specifying an offset, the byteOffset property returns 0: JavaScript DataView byteOffset Example ...
Read MoreAtomics.xor() function in JavaScript
The Atomic object of JavaScript is an object that provides atomic operations such as add, sub, and, or, xor, load, store etc. as static methods. These methods are used with SharedArrayBuffer objects for thread-safe operations in multi-threaded environments. The xor() function of the Atomics object accepts an array, position, and value, then performs a bitwise XOR operation on the value at the given position atomically. Syntax Atomics.xor(typedArray, index, value) Parameters typedArray - A shared integer typed array (Int8Array, Uint8Array, Int16Array, etc.) index - The position in the array to operate on value ...
Read MoreDataView.buffer property in JavaScript
The buffer property of the DataView represents the ArrayBuffer of the current DataView. This property provides access to the underlying buffer that the DataView is viewing. Syntax dataView.buffer Return Value Returns the ArrayBuffer that was used to create the DataView instance. Example The following example demonstrates how to access the underlying ArrayBuffer through the buffer property: JavaScript Example var arrayBuffer = new ArrayBuffer(156); ...
Read MoreWrite a program to find the index of particular element in an array in javascript?
Finding the index of a particular element in an array is a common task in JavaScript. An array is an object that contains multiple values in a sequential order, with each element having a specific index position. 22 45 67 89 12 0 1 2 3 4 Array Elements Index ...
Read MoreWrite a number array and using for loop add only even numbers in javascript?
In JavaScript, you can iterate through a number array and add only the even numbers using various loop methods. An even number is any integer that is divisible by 2, meaning when divided by 2, the remainder is 0. What are Even Numbers? Even numbers are integers that can be divided by 2 without leaving a remainder. We can check this using the modulo operator (%): if(number % 2 == 0) { // Number is even } Using for Loop The for loop is the most common way to iterate ...
