如何处理js文件中的未使用变量eslint错误？

Question

I have two different js files one is called alert.js

alert.js

 function alerts(){ alert('HI'); } 

Another one is called draw.js

 function call_alert(){ alerts(); } 

Functionally its working well, but in validation using jslint or eslint shows me these errors:

• 'alerts' is defined but never used. (no-unused-vars) (this error for alert.js file)
• 'call_alert' is defined but never used. (no-unused-vars) (this error for draw.js file)

Answer 1

When you have functions or variables that are defined in the global scope in one file but used in another, you can use exported comments to tell ESLint that they're intended to be used elsewhere. (Note that this doesn't apply to Node.js or ES modules, which don't have global scope.)

/* exported alerts */
function alerts() {
    alert('HI');
}
