To solve this problem, we will use a hash map (i.e javascript object) to store the indices of the numbers as we iterate through the array. this allows us to check if the complement of the current number (i.e., target nums[i]) exists in the map. Since an array's length can change at any time, and data can be stored at non contiguous locations in the array, javascript arrays are not guaranteed to be dense; this depends on how the programmer chooses to use them. Arrays are one of the most powerful features in javascript, and mastering array methods will make your coding much easier and more efficient. Whether you are an experienced programmer or not, this website is intended for everyone who wishes to learn the javascript programming language. just click on the chapter you wish to begin from, and follow the instructions.
