Who is this course for? 🧐

What can you expect to learn? 📚 Our course is structured into three key sections:

1. Basics of Arrays: We'll kick off by covering the essentials, including how to declare an array and understanding the different types of arrays available in JavaScript.
2. Properties of Arrays: You'll discover the core properties that every JavaScript developer should know, such as length, prototype, and constructor.
3. Methods of Arrays: This is where you'll dive into the powerful methods that arrays offer - from mutator to accessor and iteration methods, we'll cover them all.

Detailed Course Breakdown: 🎥

1. Basics of Arrays

   • Understanding Array Declaration
   • Exploring Array Types and Indexing

2. Properties of Arrays

   • length: Learn how to retrieve the number of elements in an array.
   • prototype: Explore the prototype property of arrays.
   • constructor: Find out what constructor means for your arrays.

3. Mutator Methods

   • copyWithin(): Copy elements within a section of an array.
   • fill(): Fill an array with a static value.
   • push()/pop(): Add or remove elements from the end of an array.
   • reverse(): Reverse the order of the elements in an array.
   • shift()/unshift(): Modify the start of an array.
   • splice(): Remove or replace elements from an array.
   • sort(): Sort an array's elements according to a comparator function.

4. Accessor Methods

   • concat(): Combine two or more arrays.
   • flat(): Flatten nested and/or nested arrays down to a specified depth.
   • includes(): Determine whether an array includes a certain element.
   • join(): Join all the elements of an array into a single string.
   • slice(): Extract a portion of an array without mutating it.
   • toString(): Convert the entire array into a string.
   • indexOf()/lastIndexOf(): Return the first or last index at which a given element can be found in an array.

5. Iteration Methods

   • entries(), keys(), and values(): Iterate over the key (the index of the elements), key-value pairs, and array values respectively.
   • every(): Determine if all elements in an array pass a test.
   • filter(): Create a new array with all elements that pass a test.
   • find()/findIndex(): Return the value or index of the first element in the array that satisfies the provided testing function.
   • map(): Transform each element of an array according to a callback function.
   • some(): Determine if at least one element in the array passes a test.
