Message
SyntaxError: identifier starts immediately after numeric literal (Firefox) SyntaxError: Unexpected number (Chrome)
Error type
What went wrong?
The names of variables, called identifiers, conform to certain rules, which your code must adhere to!
A JavaScript identifier must start with a letter, underscore (_), or dollar sign ($). They can't start with a digit! Only subsequent characters can be digits (0-9).
Examples
Variable names starting with numeric literals
Variable names can't start with numbers in JavaScript. The following fails:
var 1life = 'foo'; // SyntaxError: identifier starts immediately after numeric literal var foo = 1life; // SyntaxError: identifier starts immediately after numeric literal
You will need to rename your variable to avoid the leading number.
var life1 = 'foo'; var foo = life1;
