Can you explain the difference between call and apply in JavaScript?
Sure! Both call
and apply
are methods used to invoke functions with a specific this
context. The main difference is in how they pass arguments.
How do they differ in terms of argument passing?
With call
, you pass arguments individually, like func.call(thisArg, arg1, arg2)
. With apply
, you pass an array of arguments, like func.apply(thisArg, [arg1, arg2])
.
Can you give me an example of each?
Of course! For call
: function greet() { console.log(this.name); } greet.call({name: 'Alice'});
For apply
: greet.apply({name: 'Bob'}, []);
Both will log the respective names.
