    No, but you can have an Object with a bunch of properties. `const name = {}; name[Math.floor(Math.random()*Date.now())] = {data:'blah blah blah'}` Keep in mind that numeric Object properties which are not instanceof Array will be converted to Strings, though. – StackSlave Feb 06 '20 at 02:21
  • Why do you think you need this? You typically can do what stackslave suggested – Ruan Mendes Feb 06 '20 at 02:26
  • But yes, eval does what you are asking for if you have complete control of the input – Ruan Mendes Feb 06 '20 at 02:30

you can use eval():

var k = 'value'; 
var i = 0; 
for(i = 1; i < 5; i++) { 
    eval('var ' + k + i + '= ' + '{ abc: ' + i + ' }'  + ';'); 
} 
alert(value1.abc); 
alert(value2.abc); 
alert(value3.abc); 
alert(value4.abc);

or Window object:

var i; 
for(i = 1; i < 5; i++) { 
    window['value'+ i ] = { abc: i}; 
} 

alert(value1.abc); 
alert(value2.abc); 
alert(value3.abc); 
alert(value4.abc);

  • The window suggestion will always create global variables, but what the OP posted could create local variables if within functions. It also doesn't work on nodeJS. – Ruan Mendes Feb 06 '20 at 02:28

You can't do this for the variable itself, but you could have an object with random fields.

var myValues = {
  ["name" + Math.random()]: "blah"
}
