In JavaScript, in addition to using loops, you can also use built-in array methods, which provide a preset way of performing iteration on arrays
These built-in array methods are called iteration methods (aka iterators)
Commonly used iteration methods:
.forEach()- return value:undefined.map()- return value:new array.filter()- return value:new array.findIndex()- return value:index number.reduce()- return value:a single value.some()- return value:boolean.every()- return value:boolean
All iteration methods in JavaScript take in a callback function
Syntax and other information on how to use the iteration methods can be found in the MDN documentation for each array method
