What is an iteration ?

An Iteration in computer science is a function that repeats a block of code in a specified order, often until a specific result occurs. Algorithms use iterations to run a program repeatedly until it meets certain conditions or until the algorithm repeats a set number of times.

In JavaScript, an object is a standalone entity, with properties and type. Compare it with a cup, for example. A cup is an object, with properties. A cup has a color, a design, weight, a material it is made of, etc. The same way, JavaScript objects can have properties, which define their characteristics.
