Variable names in JavaScript shouldn't begin with a number (0-9). They have to start with a letter or an underscore. For instance, 123 test is not a suitable variable name, although _123 test is.

As long as you adhere to a few guidelines, variable names may be rather flexible: They should begin with a letter, an underscore (_), or a dollar symbol ($). You have the option of using numbers, letters, underscores, or dollar signs after the first letter. Use none of the reserved keywords in JavaScript.
