By the end of this project, you will have used JavaScript methods to manipulate the elements in an array. Methods can be used to add new elements to an array and to remove unwanted elements. Methods can also be used to create a new array by copying elements from one or more existing arrays. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
