Create a cityscape using functions and parameters!To do this, you need to write a function called drawBuilding$()$ that draws a $($rectangle$)$ building. This function should take as parameters the width of the building, the height of the building, and the x$-$position of the building $($remember where rectangles positions are anchored!$).$drawBuilding$($buildingWidth$,$ buildingHeight, buildingX$)$;JavaScriptYou also need to define a drawLightPole$()$ function that is called when the building is taller than $200,$ as stored in LIGHT$\_$REQUIRED$\_$HEIGHT. This light pole is made of a skinny $($rectangular$)$ pole with a circle warning light on top. The function should take in the parameters of the x$-$position, y$-$position, and height of the pole.drawLightPole$($poleX$,$ poleY, poleHeight$)$;JavaScriptOther Requirements:The bottom of all buildings should be located on the bottom edge of the canvas.The height of the pole is $1/6$th the height of the building it is sitting on$.$The width of the pole is $5,$ as assigned to POLE$\_$WIDTH, and should be centered horizontally on the top of the building.The warning light is a green circle of radius $10,$ sitting directly on top of the pole $($the middle of the circle should be located at the center of the top of the pole.$)$IMPORTANT:In order to pass the test cases and the assignment, you must include a building with the following arguments:drawBuilding$(100,350,225)$;Other than that, draw as many buildings as youd like! Below is an example of what your city could look like. Again, you only need the above building to pass the Test Cases, the rest is up to you!Challenge:Try adding windows and a door to your buildings! Get creative, use if$/$else statements to place features on some buildings and not others.
