eclipse - Javascript : Syntax error on token "delete", StringLiteral? -

    var testfunction = function () {          return {            delete: function() { // line 1                 //             }         };     }

getting below error on line 1 in eclipse

    syntax error on token "delete", stringliteral

as changed "delete" "delete1" , error goes away . delete reserved keyword ?

yes, delete reserved keyword, used remove property in object, not iterable anymore. thus, given:

var = { b: 5 }; delete a.b; console.log(a); // logs {}

it can used remove "global variables" properties of global object too, is:

delete a; // in browsers equal delete window.a;

notice can use delete property name too, need quote it:

var obj = {     'delete': function() { // line 1         //     } }; obj['delete']();
