javascript - Why does an array with a variable name of 'names' turn into a string when i put in 'name'? -

i declared array called names. used while loop go on each name , log them console. then, accidentally mistyped 'names' 'name'. normally, gives out reference error, logged different characters of first name. , checked developer tools , looked variable "name" because did not define variable **"name"

 var names = ['john', 'jane', 'mary', 'mark', 'bob'];   var = 0;  while (i < names.length) {        console.log(name[i]);        i++;  } 

what printed out in console

    j     o     h     n     , 

then looked variable "name" cos did not declare , came out

    names     "john,jane,mary,mark,bob" 

what reason behind this?

first of added simple console.log() see name is. in case did not define variable name, default shorthand variable window.name. explains behaviour, there no reference error. lets take closer it:

var names = ['john', 'jane', 'mary', 'mark', 'bob'];    var = 0;  console.log(name);  var charactersthatwillbeshown = name.substr(0, names.length);  console.log(charactersthatwillbeshown);  var loggedcharacters = "";  while (i < names.length) {     loggedcharacters += name[i];     console.log(name[i]);     i++;  }  console.log(loggedcharacters);  console.log(charactersthatwillbeshown == loggedcharacters);
