Formatting dynamic json array JavaScript

JavascriptWeb DevelopmentObject Oriented Programming

Let’s say, we have an array of objects like this −

const arr = [
   {"name1": "firstString"},
   {"name2": "secondString"},
   {"name3": "thirdString"},
   {"name4": "fourthString"},
   {"name5": "fifthString"},
   {"name6": "sixthString"},
];

We are required to write a function that takes one such array of objects and returns an object with all the properties listed in that object.

So, let’s write the code for this function. It can be done through the Array reduce method −

Example

const arr = [
   {"name1": "firstString"},
   {"name2": "secondString"},
   {"name3": "thirdString"},
   {"name4": "fourthString"},
   {"name5": "fifthString"},
   {"name6": "sixthString"},
];
const reduceArray = arr => {
   return arr.reduce((acc, val) => {
      Object.assign(acc, val);
      return acc;
   }, {});
};

Output

The output in the console will be −

{
   name1: 'firstString',
   name2: 'secondString',
   name3: 'thirdString',
   name4: 'fourthString',
   name5: 'fifthString',
   name6: 'sixthString'
}
