Data structures are used to store and organize data in a computer so that it can be accessed and manipulated efficiently.
Data structures in JavaScript include arrays, objects, sets, and maps.
Arrays are used to store a collection of elements, accessed by index.
Objects are used to store key-value pairs.
Sets are used to store unique values.
Maps are used to store key-value pairs with keys of any type.
In React Native, timers can be implemented using the setTimeout and setInterval functions.
Use setTimeout for a one-time delay before executing a function.
Use setInterval for executing a function repeatedly at a specified interval.
Remember to clear the timer using clearTimeout or clearInterval when no longer needed.
Count occurrences of elements in an array of strings
Iterate through the array and use a hashmap to store the count of each element
Use a for loop to go through each element and increment the count in the hashmap
Return the hashmap with element counts

Closures are functions that have access to variables from their outer scope even after the outer function has finished executing.

They can access variables from the outer function even after the outer function has returned.
Closures are commonly used in event handlers and callbacks in JavaScript.
Event loop is a mechanism that allows JavaScript to perform non-blocking operations by handling asynchronous events.
Event loop is responsible for executing code, collecting and processing events, and executing queued sub-tasks.
ES5 features include strict mode, JSON object, Array methods like forEach, map, filter, and reduce, and Object.create method.
