Find index is used to return the position of an element. It returns the value (-1) if the requested element is not found.

var index = $scope.items.findIndex(record => record.date ==’2018-12-12′);
In the given code, index of the object is returned where item.date=2018-12-12.

In AngularJS, there is no specific “find index” function as part of the core AngularJS framework. However, you might be referring to a common JavaScript method called indexOf().

The indexOf() method is not AngularJS-specific but is part of JavaScript arrays. It is used to find the index of the first occurrence of a specified element in an array. If the element is not found, the method returns -1.

For example:

javascript

var myArray = [10, 20, 30, 40, 50];
var index = myArray.indexOf(30);

// index will be 2, as 30 is at the third position (index 2) in the array

If the element is not present in the array, it returns -1:

javascript

var myArray = [10, 20, 30, 40, 50];
var index = myArray.indexOf(60);

// index will be -1, as 60 is not present in the array
