javascript - Custom printing from console.log? -

let's have class.

class attribute {   constructor(name) {     this.name = name;   } } 

and create instance , log console debugging purposes.

const test = new attribute('large'); console.log(test); 

how can output specially formatted string, {attribute} large? i'm concerned chrome support, node , other browsers nice, too.

class attribute {   constructor(name) {     this.name = name;   }   tostring(){//simply set string method?     return "{attribute} "+this.name;   } } 

as console.log not call string either do:

const test = new attribute('large'); console.log(test+""); 

or create own logging function
