The following parameters are accepted by this procedure, as listed above and described below:įunction: This is the array’s function that works on each element.ĬurrentValue: The current element is stored in this parameter. Index: This is an optional parameter that holds the current element’s index.Īrr: It’s a parameter that holds the array object to which the current element belongs. If a value is supplied to the function as its “this” value, otherwise the value “undefined” is passed as its “this” value. If any of the elements in the array satisfy the condition, it returns the array element value otherwise, it returns undefined.
