...
foo = [];
// vs

.clear() will remove data from list with the same reference and foo = [] will have clear data with new reference
Note: .clear() is the best option
var list_name = new List()
--- creates a list of size zero
list_name = [val1,val2,val3]
--- a list containing the specified values
list_name = []
--- clear elements with new reference
list_name.clear()
--- removes every element from the list, but retains the list itself and it's type cast. --- it's best option to remove all elements of list.
