@babel/plugin-proposal-function-bind

Function Binding

This feature allows you to bind a function to a specific context using the bind operator (::). In this example, the greet function is bound to the obj context, so it correctly logs 'Hello, Alice!'.

const obj = {
  name: 'Alice',
  greet() {
    console.log(`Hello, ${this.name}!`);
  }
};

const greet = obj.greet::obj;
greet(); // Output: Hello, Alice!

Partial Application

This feature allows you to create partially applied functions using the bind operator (::). In this example, the add function is partially applied with the value 5, creating a new function add5 that adds 5 to its argument.

function add(a, b) {
  return a + b;
}

const add5 = add.bind(null, 5);
console.log(add5(10)); // Output: 15
