What is the primary use of a "for" loop in JavaScript?

  • Iterating over an array
  • Defining a variable
  • Printing to the console
  • Adding new elements to an object
The primary use of a "for" loop in JavaScript is to iterate over an array or any iterable data structure. It allows you to repeatedly execute a block of code for each item in the iterable, making it a powerful tool for tasks like data processing, manipulation, and rendering in web applications. "for" loops are not typically used for defining variables, printing to the console, or adding new elements to an object.
