Example 1: Add Key/Value Pair to an Object Using Dot Notation // program to add a key/value pair to an object const person = { name: 'Monica', age: 22, gender: 'female' } // add a key/value pair person.height = 5.4; console.log(person); Run Code Output { name: "Monica"...
On each iteration, we add a new key-value pair to the current object, in place. #Add a Key/Value pair to all Objects in an Array using aforloop You can also use a basicforloop to add a key-value pair to all objects in an array. ...

A key-value pair. Keys define the piece of information needed and the value provides that information. The key is separated from the value by an equal sign (=). A question mark (?) to signify the beginning of the key-value pairs in the query string. ...
This function had two parameters: obj (the accumulator) and arrValue (the current element in the array). In this callback function, we set obj[arrValue] to 0, effectively creating a key-value pair in the obj object. The key was the current element from arr1, and the value was 0. ...
