javascript only: This quarter, your team manager is awarding commission to anyone who closes a sale worth $15,000 or more! The commission amount will be 10% of the value of their largest sale. Anyone who does not make this large of a sale will receive the base commission of $500. Write a function `salesCommission(arr)` that takes an array of objects containing salesperson names and their largest sale, and returns the total amount of commission money that needs to be paid out to the team. Example: salespeople = [ { name: "Susan", largestSale: 3000 }, { name: "Brianna", largestSale: 20000 }, { name: "Dwayne", largestSale: 13000 }, { name: "Delilah", largestSale: 26000 }, { name: "Fernando", largestSale: 8000 }, ]; console.log(salesCommission(salespeople)); // 6100

In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by “O”) at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection (“Left”, “Right”, “Up”, or “Down”). Based on these directions, you will try tomove the player.• If the location is valid (represented by “_”), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by “X”), you will tell the…

Return the First Element in an Array JavaScript Create a function that takes an array containing only numbers and return the first element. Examples getFirstValue ([1, 2, 3]) → 1 getFirstValue ([80, 5, 100])→ 80 getFirstValue ([-500, 0, 50])-500
