Javascript-new users: front-end Interaction

At the front end of the entry line, the page can be written, but it will be dizzy when it comes to collaboration with the backend. Recently, there is a need to determine whether a person has received a prize or not, my colleague told me that this is what he did. He gave me a variable and asked me to judge this variable?

Making a variable is similar
Script var hasUsed = ; Script

You have obtained this variable.hasUsedMake a judgment.

You can reserve a location for his variable in your code, for example:

《script》var countTime = 
  ;《script》

The The variable that your colleague calls will become

《script》var countTime = 5;《script》

You can do this during development.

《script》var countTime = 5;//
  ;《script》

In this way, you can test your code Logic first. If everything is okay, it will be done by restoring it to Example 1. It's easy.

I will try it out. I will try it for you.

The question you asked is too easy to get started. I don't want to ask my colleagues modestly.
