javascript - node.js not working Object.keys -

- 

var list = {"you": 100, "me": 75, "foo": 116, "bar": 15}; keyssorted = object.keys(list).sort(function(a,b){return list[a]-list[b]}) alert(keyssorted);     // bar,me,you,foo

from sorting javascript object property value

i'm doing object sorting. above source working in javascript. not working in node.js. have error this.

keyssorted = object.keys(list).sort(function(a,b){return list[a]-list[b]})                     ^ typeerror: object.keys not function

i don't know why. please me.

most likely, using out-dated node.js version, v0.10 or v0.12. check version try running node -v.

this old version doesn't support object.keys. can check supported features every node.js versions here.

my advice update node.js version 6.9.1. version current lts (long-term support).

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
