What is the difference between call and apply?
Explanation
The difference between call and apply is that apply will allow you to invoke the function with arguments as an array. Whereas the call will require the parameters that can be listed explicitly.
See MDN’s documentation on apply and call.
Pseudo syntax:
theFunction.apply(valueForThis, arrayOfArgs)
theFunction.call(valueForThis, arg1, arg2, ...)
Here we have a Sample code:
function theFunction(name, profession) {
console.log("My name is " + name + " and I am a " + profession +".");
}
theFunction("John", "fireman");
theFunction.apply(undefined, ["Susan", "school teacher"]);
theFunction.call(undefined, "Claude", "mathematician");
theFunction.call(undefined, ...["Matthew", "physicist"]); // used with the spread operator
