giving a variable name with variable javascript code example

Example 1: javascript dynamic variable name

var obj = {
  'prop1' : 'test1',
  'prop2' : 'test2'
}

var keys = Object.keys(obj);

for (let i = 0; i < keys.length; i++) {
  var key = keys[i];
  
  // Here you can use a string value as the property name
  var prop = obj[key];
}

Example 2: how to name a javascript variable

//variables can include any letter, any number, or the underscore
	//NO SPACES!!! USE UNDERSCORES!!!
	//variable names are case sensitive
	//example:
var change_this = 'whatever you want here'
	//change_this is a variable (change it to your variable name)
	//'whatever you want here' is a string (you'll learn about this later)
