All bosses: arrays, averaging, in several ways, finally the results returned to NAN, and what the so-CodePudding

 
Var arr=[4000500, 0140, 00900]; 
Var getAvg=function (array) {
Var len=array. Lenght; 
Var sum=0; 
for(var i=0; iThe sum +=array [I]; 
} 
Return the sum/len; 
} 
The console. The log (getAvg (arr));
