"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
