Arrange oven racks in the upper and middle positions of the oven. Heat the oven to 375°F and grease two baking sheets.
Using a mixer fitted with a paddle, beat together the butter, granulated sugar, and brown sugar on high until light and fluffy, about 1 minute. Scrape the bowl and beater. Add the eggs and vanilla and beat on low until blended. Beat on high until light and fluffy, about 1 minute. Scrape the bowl and beater.
In a medium bowl, whisk together the flour, salt, and baking soda. Add this to the butter mixture and beat on medium low until just blended. Stir in the chocolate chips with a wooden spoon.
Drop rounded measuring tsp. of dough 2 inches apart onto the greased baking sheets. Bake until deep golden brown around the edges and golden in the center, 8 to 10 minutes, rotating the baking sheets halfway through for even results. Remove the sheets from the oven, let sit for 3 to 5 minutes, and then transfer the cookies with a spatula to a wire rack to cool completely. Repeat until all the dough is baked.
