ECMAScript 2023 introduces changes to JavaScript that make programming easier. The changes include the Object.groupBy method for grouping objects based on a property value, the Array.toSliced(), Array.toSorted(), and Array.toReversed() methods for manipulating arrays without mutating the original array, and the findLast() and findLastIndex() methods for finding the last element or index in an array that satisfies a condition.
