+### esutils [![Build Status](https://secure.travis-ci.org/estools/esutils.svg)](http://travis-ci.org/estools/esutils)
+esutils ([esutils](http://github.com/estools/esutils)) is
+utility box for ECMAScript language tools.
+
+### API
+
+### ast
+
+#### ast.isExpression(node)
+
+Returns true if `node` is an Expression as defined in ECMA262 edition 5.1 section
+[11](https://es5.github.io/#x11).
+
+#### ast.isStatement(node)
+
+Returns true if `node` is a Statement as defined in ECMA262 edition 5.1 section
+[12](https://es5.github.io/#x12).
+
+#### ast.isIterationStatement(node)
+
+Returns true if `node` is an IterationStatement as defined in ECMA262 edition
+5.1 section [12.6](https://es5.github.io/#x12.6).
+
+#### ast.isSourceElement(node)
+
+Returns true if `node` is a SourceElement as defined in ECMA262 edition 5.1
+section [14](https://es5.github.io/#x14).
+
+#### ast.trailingStatement(node)
+
+Returns `Statement?` if `node` has trailing `Statement`.
+```js
+if (cond)
+    consequent;
+```
+When taking this `IfStatement`, returns `consequent;` statement.
+
+#### ast.isProblematicIfStatement(node)
+
+Returns true if `node` is a problematic IfStatement. If `node` is a problematic `IfStatement`, `node` cannot be represented as an one on one JavaScript code.
+```js
+{
+    type: 'IfStatement',
+    consequent: {
+        type: 'WithStatement',
+        body: {
+            type: 'IfStatement',
+            consequent: {type: 'EmptyStatement'}
+        }
+    },
+    alternate: {type: 'EmptyStatement'}
+}
+```
+The above node cannot be represented as a JavaScript code, since the top level `else` alternate belongs to an inner `IfStatement`.
+
+
+### code
+
+#### code.isDecimalDigit(code)
+
+Return true if provided code is decimal digit.
+
+#### code.isHexDigit(code)
+
+Return true if provided code is hexadecimal digit.
+
+#### code.isOctalDigit(code)
+
+Return true if provided code is octal digit.
+
+#### code.isWhiteSpace(code)
+
+Return true if provided code is white space. White space characters are formally defined in ECMA262.
+
+#### code.isLineTerminator(code)
+
+Return true if provided code is line terminator. Line terminator characters are formally defined in ECMA262.
+
+#### code.isIdentifierStart(code)
+
+Return true if provided code can be the first character of ECMA262 Identifier. They are formally defined in ECMA262.
+
+#### code.isIdentifierPart(code)
+
+Return true if provided code can be the trailing character of ECMA262 Identifier. They are formally defined in ECMA262.
+
+### keyword
+
+#### keyword.isKeywordES5(id, strict)
+
+Returns `true` if provided identifier string is a Keyword or Future Reserved Word
+in ECMA262 edition 5.1. They are formally defined in ECMA262 sections
+[7.6.1.1](http://es5.github.io/#x7.6.1.1) and [7.6.1.2](http://es5.github.io/#x7.6.1.2),
+respectively. If the `strict` flag is truthy, this function additionally checks whether
+`id` is a Keyword or Future Reserved Word under strict mode.
+
+#### keyword.isKeywordES6(id, strict)
+
+Returns `true` if provided identifier string is a Keyword or Future Reserved Word
+in ECMA262 edition 6. They are formally defined in ECMA262 sections
+[11.6.2.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-keywords) and
+[11.6.2.2](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-future-reserved-words),
+respectively. If the `strict` flag is truthy, this function additionally checks whether
+`id` is a Keyword or Future Reserved Word under strict mode.
+
+#### keyword.isReservedWordES5(id, strict)
+
+Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 5.1.
+They are formally defined in ECMA262 section [7.6.1](http://es5.github.io/#x7.6.1).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is a Reserved Word under strict mode.
+
+#### keyword.isReservedWordES6(id, strict)
+
+Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 6.
+They are formally defined in ECMA262 section [11.6.2](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-reserved-words).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is a Reserved Word under strict mode.
+
+#### keyword.isRestrictedWord(id)
+
+Returns `true` if provided identifier string is one of `eval` or `arguments`.
+They are restricted in strict mode code throughout ECMA262 edition 5.1 and
+in ECMA262 edition 6 section [12.1.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-identifiers-static-semantics-early-errors).
+
+#### keyword.isIdentifierName(id)
+
+Return true if provided identifier string is an IdentifierName as specified in
+ECMA262 edition 5.1 section [7.6](https://es5.github.io/#x7.6).
+
+#### keyword.isIdentifierES5(id, strict)
+
+Return true if provided identifier string is an Identifier as specified in
+ECMA262 edition 5.1 section [7.6](https://es5.github.io/#x7.6). If the `strict`
+flag is truthy, this function additionally checks whether `id` is an Identifier
+under strict mode.
+
+#### keyword.isIdentifierES6(id, strict)
+
+Return true if provided identifier string is an Identifier as specified in
+ECMA262 edition 6 section [12.1](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-identifiers).
+If the `strict` flag is truthy, this function additionally checks whether `id`
+is an Identifier under strict mode.
