angular - Typescript `super` calling from overridden method -


recently found issue in project, here example code (angular 2.3 context):

export class httpservice extends http {     ...     request(url: string, requestoptions?: requestoptionsargs, config: = {}) { // method overridden         ...         return super.request(url, options) // called http.request()      }     getoptions() {         ...         super.request(url, options) // called this.request()     } }

can explain why in 1st case called method super expected, in 2nd case called this (found in debug console)?

super still follows prototypical-inheritance rules. meaning try find request first in httpservice.prototype , if doesn't find there go down prototype chain.

here more information behavior: http://2ality.com/2015/02/es6-classes-final.html#referring-to-super-properties-in-methods

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
