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.

Skills you will develop

  • Merge arrays
  • JS Arrays
  • toString()
  • JS Methods
  • JavaScript

Learn step-by-step

In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:

  1. Use the toString() method to extract all of the elements in the array and place them into a string with the elements separated by commas.

  2. Use the push(), unshift(), and splice() methods to include a new element to the end of an array.

  3. Use the pop(), shift() and splice() methods to remove the elements from an array.

  4. Use the slice() method to copy elements from an existing array into a new array.

  5. Use the concat() method to create a new array by merging the contents of two existing arrays.
