No, JavaScript (and most other programming languages) does not allow variable names with spaces. For your example, it will read the variable name as "your", and then throw an error at "name" because it does not recognize that as valid syntax. Instead, you could do var yourName = "arun" or var your_name = "arun". Hope this helped! :)

Hi Arun,

Spaces can't exist in variable names as the syntax is invalid, you can use either an underscore or camel casing instead like in the below example.

var your_name = '';
var yourName = '';
