| // Assume a large array as the main argument with the following schema and manipulate accordingly. | |
| // EXAMPLE SCHEMA: | |
| // name: String | |
| // weight: Number | |
| // price: Number | |
| // size: Number | |
| // id: Number | |
| // EXERCISE #1 | |
| // Return an Array of products priced greater than or equal to 75. | |
| const highPricedProducts = products => { | |
| return products.filter(product => product.price >= 75); | |
| }; | |
| // EXERCISE #2 | |
| // Return an Array of products that are heavier than 1.8 | |
| const heavyProducts = products => { | |
| return products.filter(product => product.weight > 1.8); | |
| }; | |
| // EXERCISE #3 | |
| // Cast the Array into an Object where Keys become the ID's and the Values are the remaining Object Properties | |
| // Keys should be iterable E.G. Object.keys(obj).map() | |
| // Values should be searchable either numeric or string Keys E.G. obj[0], obj['0'] | |
| const arrayToObject = products => { | |
| let obj = {}; | |
| for (let i = 0; i < products.length; i++) { | |
| obj[i] = products[i]; | |
| } | |
| return obj; | |
| }; |
