If it had been, this would violate the constraint of the structured clone algorithm wherein object references cannot be shared between threads. Shared Memory in Node.js The Node.js equivalent of this application is mostly similar; however, the Worker global provided by browsers isn’t available,...
If we need the max/min values after every iteration and for that if we need to sort an array in a loop, it can be simplified using a priority queue or heap Eg -last stone weight Use greedy algorithm for problems of the kinds where we first fill the jar with stones, then pebbles, a...
Creates a hash for a value using the SHA-256 algorithm. Returns a promise. Use the SubtleCrypto API to create a hash for the given value. const hashBrowser = val => crypto.subtle.digest('SHA-256', new TextEncoder('utf-8').encode(val)).then(h => { let hexes = [], view = new...
By default the plugin uses AES-256 as the encryption cypher algorithm. To enable the encryption plugin in the persistent storage module you must add it as a transcoder step: db.persist.addStep(new db.shared.plugins.FdbCrypto({ pass: "testing" })); The plugin accepts an options object ...
37. Sort Array of Objects by Properties Write a JavaScript program to get a sorted array of objects ordered by properties and orders. Click me to see the solution 38. Pad String on Both Sides Write a JavaScript program to pad a string on both sides with the specified character, if it's...
This method has the same algorithm as Array.prototype.some(). TypedArray is one of the typed array types here. some: The some() method tests whether some element in the array passes the test implemented by the provided function. sort: The sort() method sorts the elements of an array ...
Shuffle the array using the Fisher-Yates algorithm. Use Array.slice() to get the first n elements. Omit the second argument, n to get only one element at random from the array. const sampleSize = ([...arr], n = 1) => { let m = arr.length; while (m) { const i = Math.floo...
Returns a sorted array of objects ordered by properties and orders.Uses a custom implementation of sort, that reduces the props array argument with a default value of 0, it uses destructuring to swap the properties position depending on the order passed. If no orders array is passed it sort ...
Transforms[ ]An ordered array of transform algorithm URIs. These are the one or more method(s) used to process the Reference element before the data object associated therewith is digested. An output of a transform may be supplied as an input to another. This element is optional. ...
