Unnecessary calls to .bind() should not be used.
Why is this an issue?
The .bind() method allows specifying the value of this and, optionally, the values of some function arguments. However,
if this is not used in the function body, calls to .bind() do nothing and should be removed.
Calling .bind() on arrow functions is a bug because the value of this does not change when .bind() is
applied to arrow functions.
How to fix it
Remove calls to .bind() method.
Code examples
Noncompliant code example
let x = function fn() {
return 123;
}.bind({value: 456}); // Noncompliant
let y = (() => this.body).bind(document); // Noncompliant
Compliant solution
let x = (function callback() {
return this.body;
}).bind(document); // ok, not an arrow function
let y = (function print(x) {
console.log(x);
}).bind(this, foo); // ok, binds argument
