Explicit binding is a way to explicitly state what the this keyword is going to be bound to using call, apply or bind methods of a function.

const roadmap = {
  name: 'JavaScript',
};

function printName() {
  console.log(this.name);
}

printName.call(roadmap); // JavaScript
printName.apply(roadmap); // JavaScript

const printRoadmapName = printName.bind(roadmap);
printRoadmapName(); // JavaScript

In the above example, the this keyword inside the printName() function is explicitly bound to the roadmap object using call, apply or bind methods.
