How to Convert an Array of Objects into One Object in JavaScript?

To convert an array of objects into one object in JavaScript, you can use various methods depending on your requirements. Here are a few approaches you can take:

Approach 1: Using Object.assign() method

The Object.assign() method can be used to combine objects into a single object. It takes one or more source objects and combines them into a target object. Here is an example of how to use this method to convert an array of objects into one object:

const arr = [{ key1: 'value1' }, { key2: 'value2' }, { key3: 'value3' }];

const result = Object.assign({}, ...arr);

console.log(result); // { key1: 'value1', key2: 'value2', key3: 'value3' }

In this example, the spread operator ... is used to pass the array of objects as separate arguments to the Object.assign() method. The empty object literal {} is used as the target object. The method then combines all objects in the array into a single object, which is assigned to the result variable.

Approach 2: Using the reduce() method

Another approach is to use the reduce() method to iterate over the array and combine the objects into a single object. Here is an example:

const arr = [{ key1…
