vari, myarray =[];for(i = myarray.length; i--;) {//do something with myarray[i]} And the second uses a whileloop: varmyarray =[], i=myarray.length;while(i--) {//do something with myarray[i]}
Here “platform code” means engine, environment, and promise implementation code. In practice, this requirement ensures that onFulfilled and onRejected execute asynchronously, after the event loop turn in which then is called, and with a fresh stack. This can be implemented with either a “macro-...

For the case of dale.stop and dale.stopNot, we set output to result. If we're in dale.stop and result is equal to second, we return true to break the loop. We do the same with dale.stopNot when result is not equal to second. Otherwise, we return false, which will do nothing....
One way to loop through an array, is using aforloop: Example constfruits = ["Banana","Orange","Apple","Mango"]; letfLen = fruits.length; lettext =""; for(leti =0; i < fLen; i++) { text +=""+ fruits[i] +""; } text+=""; Try...
Best practice: Use .skip() instead of commenting tests out. You may also skip at runtime using this.skip(). If a test needs an environment or configuration which cannot be detected beforehand, a runtime skip is appropriate. For example: ...
Odd Numbers: Display/Print all the Odd Numbers from 1 to 20 as output, using the 'while' loop. (odd.js) Display Array with Loops. (arrayLoop.js) Display every element of an array, using the 'for' loop and the 'while' loop. Display every element of an array, using the 'for' loo...
If this is done using a for loop, the calling code must be careful about how it handles closures. Finally, the app should close the File object once it’s done with it, by calling the File.closeAsync method. Only two files are allowed to remain in memory at any time; attempting to ...
First you’ll meet the for loop, which is used to execute a block of code for a specified number of times.Copy sum = 0; for (i = 1; i <= 100; i++) { sum = sum + i; } alert("Sum of first 100 numbers is: " + sum); ...
(which it should be anyway), then you can afford to relax that rule a bit and declare variables close to where they are used (e.g., inside aforloop). That better encapsulates pieces of code. Obviously, you should be aware that that encapsulation is only conceptual, because function-wide...
