deprecation

> Log a deprecation message with stack

!build

Usage

`js
function foo() {
bar();
}

function bar() {
baz();
}

function baz() {
console.warn(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}

foo();
// { Deprecation: [my-lib] foo() is deprecated, use bar()
// at baz (/path/to/file.js:12:15)
// at bar (/path/to/file.js:8:3)
// at foo (/path/to/file.js:4:3)
`

To log a deprecation message only once, you can use the once module.

`js
const Deprecation = require("deprecation");
const once = require("once");

const deprecateFoo = once(console.warn);

function foo() {
deprecateFoo(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}

foo();
foo(); // logs nothing
``
