How to access 'this' keyword inside an arrow function in JavaScript?
"this" keyword in an arrow function
The JavaScript 'this' keyword refers to the object it belongs to. In an arrow function, 'this' belongs to a global object. Inside a simple function, there might be chances that 'this' keyword can result in undefined but in an arrow function it results in an exact value.
Example
<html>
<body>
<script>
function Student(fname, grade) {
this.fname = fname;
this.grade = grade;
this.details = function() {
return () => {
document.write(`Hi, I'm ${this.fname} from ${this.grade} grade`);
};
}
}
let info = new Student('picaso', 'seventh');
let printInfo = info.details();
printInfo();
</script>
</body>
</html>
Output
Hi, I'm picaso from seventh grade
