Preheat the oven to 350 degrees F (175 degrees C).
In a large bowl, stir together the butter, white sugar and brown sugar until smooth.
Mix in eggs one at a time, then stir in the vanilla.
Combine the flour, baking soda and salt; stir into the batter just until blended, then mix in the chocolate chips so they are evenly distributed. Drop cookies by heaping teaspoonfuls onto ungreased cookie sheets spacing 2 inches apart.
Bake in the preheated oven until the edges begin to turn golden, 12 to 15 minutes. Allow cookies to cool for a few minutes on the baking sheets before removing to wire racks to cool completely.
