$ yarn add [-D] postfix.js

# or

$ npm i -D postfix.js

```

## ES6 import

``` js

import postfix, {

    stackify,

} from "postfix.js";

```

## CommonJS require

    stackify = require("postfix.js").stackify;

```

`dist/core.js` and `dist/core.min.js` are UMD bundles.

``` js

/* Using AMD require */

require([

    "https://unpkg.com/postfix.js",

], function (postfix) {

    // postfix

    // postfix.stackify

});

```

``` html

```

# Usage

``` js

postfix("60 5 7 5 - * /"); // [ 6 ]

postfix("60 5 / 7 5 - *"); // [ 24 ]

postfix("1 2 x -", {

    "x": stack => stack.reverse(),

}); // [ 1 ]

postfix("-1 abs", {

    "abs": stackify(Math.abs),

}); // [ 1 ]

```

Nativly supported operations: `+`, `-`, `*`, `/`, `%` and `^` (`Math.pow`)
