Tips for accessing a specific value within an array of objects using a key

Is there a way to retrieve the value in an object array based on a key that is present within the same array?

The structure of the object array is as follows:

const objectArray = [
    {key: "1", value: "12321"},
    {key: "2", value: "asdfas"}
]

For example, if I have the key's value as key = 1, how can I obtain 12321 as the desired output? Are there any solutions available for this scenario?

Answer №1

If you want to accomplish this task, you can utilize the .find() method.

Give this a try:

Check out the Demo

this.objectArray.find(x => x.key == "1").value

To address any potential exceptions if the item is not found in the array, follow this approach:

let item = this.objectArray.find(x => x.key == "1")
this.value = item ? item.value : null

Answer №2

You have the ability to achieve this by utilizing the filter() function and leveraging the existing key value.

const objectArray = [
    {key: "1", value: "12321"},
    {key: "2", value: "asdfas"}
]

const el = objectArray.filter(item => item.key == 1)[0];

el
  ? console.log(el.value) // will output 12321
  : console.log('none found')

Answer №4

arrayOfObjects.forEach(function(element) {
    Object.keys(element).forEach(function(prop) {
        console.log("property:" + prop + "value:" + element[prop]);
    });
});
