Angular2: ts - Supplied parameters do not match any signature of call target

Below is the code that has the logic that changes the rows, cols, according to my business needs. When I keep this code, in my Angular2 ts code, I am getting Supplied parameters do not match any signature of call target error at .forEach(...

var data = [{ Id: "a", ColumnLocation: "0", RowLocation: "0" }, { Id: "b", ColumnLocation: "0", RowLocation: "1" }, { Id: "4", ColumnLocation: "0", RowLocation: "3" }, { Id: "c", ColumnLocation: "1", RowLocation: "0" }, { Id: "d", ColumnLocation: "1", RowLocation: "2" }, { Id: "e", ColumnLocation: "2", RowLocation: "0" }, { Id: "e", ColumnLocation: "2", RowLocation: "2" }];

data.forEach(function (col, row) {
                return function (o) {
                    if (col !== o.ColumnLocation) {
                        col = o.ColumnLocation;
                        row = 0;
                    }
                    if (+o.RowLocation !== row) {
                        o.RowLocation = row.toString();
                    }
                    row++;
                }
            }());

As others mentioned in order to use self executing function with parameters you need to provide those parameters.

let myCol; // or you can set this to an initial value
let myRow;

data.forEach(function (col, row) {
            return function (o) {
                // your logic here
            };
        }(myCol, myRow));

Your typescript compiler is complaining because your function takes two parameters col and row but you are invoking it without any parameter.
