Lodash _.lastIndexOf() Method
The lodash _.indexOf() method is used to get the index of the first occurrence of the particular element in the array from the last element. If fromIndex is not present in the array negative one is given as the output and no error is displayed. This method is like lodash _.indexOf except that it iterates over elements of an array from right to left.
_.lastIndexOf(array, value, [fromIndex=array.length-1])
Note: If the value is not found in the array -1 is returned.
Parameters: This method accepts three parameters as mention above and described below.
- array: It is the array in which value is to be found.
- value: It is the value to be looked in the array.
- fromIndex: It is the index after which we have to look for the value.
Return Value: It returns the index of the value in the array. If the value is not found, the array returned -1.
Example 2: Looking for a value from a particular index.
Example 3: Looking for a value that is not present.
