JavaScript

The ??= operator in JavaScript is a logical assignment operator designed to simplify the process of assigning values when dealing with null or undefined.

The &&= operator is a logical assignment operator in JavaScript that simplifies conditional assignments. This operator combines the logical AND (&&) operator with the assignment (=) operator, providing a concise way to update variables based on a condition.

The ||= operator is a logical assignment operator introduced in JavaScript that provides a concise way to assign default values when the left-hand side operand is falsy.

In modern JavaScript development, managing multiple asynchronous operations efficiently is crucial. The Promise.allSettled() method, introduced in ECMAScript 2020, provides a robust solution for handling multiple promises, offering a way to deal with all outcomes of promises without failing on the first rejected promise.

JavaScript’s Promise.any() is a powerful method for working with multiple asynchronous operations. Unlike Promise.all() or Promise.race(), which resolve or reject based on the state of all promises or the first promise, Promise.

The String.matchAll() method in JavaScript is a powerful tool that returns an iterator of all matched results of a regular expression against a string, including capturing groups.

The String.replaceAll() method in JavaScript is a powerful tool for replacing all occurrences of a substring or pattern in a string.

The JavaScript Array.at() method is a recent addition to the ECMAScript specification, designed to provide an easy and readable way to access elements in an array using positive or negative indices.

BigInt is a built-in JavaScript object that provides a way to represent and manipulate integers beyond the safe range for the Number type.

The Nullish Coalescing Operator (??) in JavaScript is a useful tool for dealing with null and undefined values. This operator provides a cleaner, more intuitive way to assign default values, making your code easier to read and maintain.

The Numeric Separator (_) in JavaScript is a feature that enhances code readability by allowing underscores to be placed within numeric literals.

The Optional Chaining Operator (?.) in JavaScript is a game-changer for handling deeply nested properties and avoiding runtime errors. This modern feature streamlines the process of accessing properties on objects that may be null or undefined, offering a cleaner and more efficient approach to safeguarding your code.

JavaScript private methods and fields provide a way to encapsulate data and functionality within a class, ensuring they are not accessible from outside the class.

The d modifier, also known as the “duplicate capturing group names” modifier, is a recent addition to the JavaScript regular expression (RegExp) syntax.

JavaScript offers multiple ways to define functions, with arrow functions being a modern addition that has gained popularity due to their concise syntax and unique behavior.

JavaScript’s evolving ecosystem continuously introduces new features to make data manipulation easier and more efficient. One such feature is the Object.

Formatting dates is a common task in JavaScript, whether you’re displaying a date on a website, generating timestamps, or working with date-related data.

JavaScript arrays are powerful structures, offering various methods to search, filter, and manipulate data. Among the more recent additions to the array toolkit is the findLast() method.

JavaScript arrays offer a variety of methods for searching and manipulating data, with the findLastIndex() method being one of the more powerful tools available.

JavaScript continues to evolve, offering developers more tools to handle arrays efficiently. One such recent addition is the toReversed() method. Unlike the traditional reverse() method, toReversed() allows you to reverse an array without mutating the original.

JavaScript arrays are powerful and versatile, and with the introduction of new methods like toSorted(), managing arrays has become even more efficient.
