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

JavaScript is an interpreted language.
JavaScript is an interpreted language, meaning it is executed line by line at runtime.
There is no separate compilation step in JavaScript like in languages that use compilers.
Examples of interpreted languages include Python, Ruby, and PHP.
Output comparison of for loops using var, let, and bind in JavaScript.
Using var: variable is function-scoped, may lead to unexpected behavior in loops.
Using let: variable is block-scoped, recommended for loop iterations.
Using bind: creates a new function with a specified 'this' value and initial arguments.
