This article introduces the knowledge of "the example usage of for...of loop in javascript". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Call the object's [Symbol.iterator] method to get the iterator and call its next method.

2. The loop determines whether the iteration is over, otherwise the value attribute value of the result is taken out.

And execute the code we wrote inside for...of.

Example

/ / for example: for (const item of obj) {console.log (item) / / traversing print each item} / / general principle: const iterator = obj [Symbol.iterator] () / / get the iterator let result = iterator.next () while (! result.done) {const item = result.value console.log (item) / / the code we wrote to print each item result = Iterator.next ()} "instance usage of for...of Loop in javascript" ends here.
