The for...of command pair iterates (loops) across any iterable's values. For each value, the code block inside the loop is executed once.
The looping constructs for..in and for..of are used to traverse across data structures. The sole distinction is the entities that they iterate over: for..in loops through all of an object's enumerable property keys. Iterates over the values of an iterable object with for..of.
Because JavaScript components are preserved as standard object properties, it is not recommended to use for...in loops to traverse through JavaScript arrays because all enumerable attributes would be listed.
A for loop continues until a condition is evaluated as false. Looping in JavaScript is analogous to looping in Java and C. When a for loop runs, it does the following: If there is one, the initialising expression initialExpression is used.
