My goal is to create a custom log method for the String object that will print out the actual string value, but I'm facing some difficulties in getting it to work correctly.
String.prototype.log = function() {
console.log(this.valueOf());
}
'Print Me'.log(); // [object Window]
I need help figuring out how to make it log 'Print Me' instead of '[object Window]'. Any suggestions?
Ah, indeed it does! The issue arises from the fact that this does not reference the string within an arrow function:
String.prototype.log = function() {
console.log(this.toString())
}
'Print Me'.log();As demonstrated, it functions properly when using a regular function. To gain further understanding, explore more about the lexical scoping of arrow functions.
The concept of context in arrow functions is vital. Arrow functions may not be suitable here as they bind to the enclosing context, which could hinder string object access.
To address this, consider implementing:
String.prototype.output = function() { console.log(this.toString()) }
