Likewise, the number to be found is stored in toFind. Now if you wants to store multiple values (10 or 15 or more different values) in different variables then it will be overhead for you to create and initialize different variables for each value. To store this data in a lookup table / map , we need to create a HashMap with key as string and then associate multiple values with same key.

A two-dimensional array is an array that contains elements in the form of rows and columns. Then, we'll show how to use container classes for complex data and learn how to create generic tuple classes. JavaScript arrays are used to save multiple values in a single variable. Strings, on the other hand, is a sequence of character.
