What are the differences between arrays and strings in JavaScript?

In JavaScript, arrays are ordered collections of items, while strings are sequences of characters. Arrays can hold multiple data types, whereas strings are immutable and represent text.

Can you give me examples of when to use an array instead of a string?

Sure! Use arrays when you need to store a list of items, like user names or numbers. Use strings for text manipulation, like displaying messages or processing user input.

Are there any methods specific to arrays that don't apply to strings?

Yes, arrays have methods like push(), pop(), and map(), which allow you to manipulate the collection. Strings have methods like charAt(), substring(), and toUpperCase() that are specific to text.

How do I convert a string to an array in JavaScript?

You can convert a string to an array using the split() method. For example, let arr = str.split(''); will create an array of characters from the string.
