Static methods in JavaScript classes?
Static methods
Using static methods, we can access only the elements in a class but not the elements in the object. It is possible to call a static method only inside a class but not in an object.
Example-1
In the following example, static() method is initiated in class "Company" rather than in an object "myComp". Therefore the contents in the static() method were executed in the output.
<html>
<body>
<p id="method"></p>
<script>
class Company {
constructor(branch) {
this.name = branch;
}
static comp() {
return "Tutorix is the best e-learning platform"
}
}
myComp = new Company("Tesla");
document.getElementById("method").innerHTML = Company.comp();
</script>
</body>
</html>Output
Tutorix is the best e-learning platform
Example-2
In the following example, instead of the class, the object is called therefore no output will be executed. If we open the browser console we can see an error stating that "myComp.comp()" is not a function.
<html>
<body>
<p id="method"></p>
<script>
class Company {
constructor(branch) {
this.name = branch;
}
static comp() {
return "Tutorix is the best e-learning platform"
}
}
myComp = new Company("Tesla");
document.getElementById("method").innerHTML = myComp.comp();
</script>
</body>
</html>
