Add an existing var to a new object in JavaScript and loop through them -

i find numerous guides on how add variables existing objects, how add "existing" variable existing object.

i have whole list variables defined in script. e.g.: a, b, c, d. , have own values. want call function on these variables , show variable-names , outcome in console. therefor want create object out of them loop through. how do this?

this workflow: values created in various places in script:

a = 1.333; b = 1.64252345; c = 2.980988; 

i create object , try add existing variables (this fail):

var abc = {}; abc.a; abc.b; abc.c; 

i want loop through object, flooring numbers, , printing variable-name returned number:

var i; (i = 0; < abc.length; ++i) {     var variablename = object.keys(abc[i]);     var flooredvalue = floor(abc[i]);     var abc[i] = flooredvalue; // save floored value variable.     console.log(variablename+": "+flooredvalue); } 

my desired output in console.log:

a = 1 b = 1 c = 2 

looping through array of object keys idea.

a = 1.333;  b = 1.64252345;  c = 2.980988;    var abc = {};  abc.a = a;  abc.b = b;  abc.c = c;    var i;  var keys = object.keys(abc);  console.log(abc['a'])  (i = 0; < keys.length; i++) {      var key = keys[i];      var flooredvalue = math.floor( abc[key] );      abc[key] = flooredvalue;      window[key] = flooredvalue; //global variable change.  }  console.log(a);  console.log(b);  console.log(c);
