JavaScript Object fromEntries() Method allows you to easily create an object from an array of key-value pairs. This method is a relatively new addition to JavaScript, introduced in ECMAScript 2019.
Object.fromEntries(iterable)This method takes an iterable such as an array and returns an object with properties corresponding to the key-value pairs. In this case, the keys are the first element of each inner array, and the values are the second element of each inner array.
JavaScript Object fromEntries() example
A simple example code has an array of key-value pairs, myArray, where each pair is an array itself. We then use the Object.fromEntries() method to convert this array of pairs into a single object, myObject.
