* `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,

* `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
* `template`, `unescape`, `uniqueId`, and `value`

It aimes to be intuitive and human readable with the ability to express any change necessary to deal with rich text. A document can also be expressed with this format--as the change from an empty document.\n\n## Quick Example\n\n```js\nvar delta = new Delta([\n { insert: 'Gandalf', attributes: { bold: true } },\n { insert: ' the ' },\n { insert: 'Grey', attributes: { color: '#ccc' } }\n]);\n\n// Keep the first 12 characters, delete the next 4, and insert a white 'White'\nvar death = new Delta().retain(12)\n .delete(4)\n .insert('White', { color: '#fff' });\n// this produces:\n// {\n// ops: [\n// { retain: 12 },\n// { delete: '4 ' },\n// { insert: 'White', attributes: { color: '#fff' } }\n// ]\n// }\n\ndelta.compose(death);\n// delta is now:\n// {\n// ops: [\n// { insert: 'Gandalf ', attributes: { bold: true } },\n// { insert: 'the ' },\n// { insert: 'White', attributes: { color: '#fff' } }\n// ]\n// }\n\n```\n\nThis format is suitable for [Operational Transform](https://en.wikipedia.org/wiki/Operational_transformation) and defines several functions to support this use case.\n\n## Contents\n\n#### [Operations](#operations-1)\n\n- [insert](#insert-operation)\n- [delete](#delete-operation)\n- [retain](#retain-operation)\n\n#### [Deltas](#deltas-1)\n\n- [`constructor`](#constructor)\n- [`insert`](#insert)\n- [`delete`](#delete)\n- [`retain`](#retain)\n- [`length`](#length)\n- [`slice`](#slice)\n- [`compose`](#compose)\n- [`transform`](#transform)\n\n#### [Documents](#documents-1)\n\n- [`diff`](#diff)\n\n\n## Operations\n\nOperations describe a singular change to a document. They can be an [`insert`](#insert-operation), [`delete`](#delete-operation) or [`retain`](#retain-operation). Note operations do not take an index. They always describe the change at the current index. Use retains to \"keep\" or \"skip\" certain parts of the document.\n\n### Insert Operation\n\nInsert operations have an `insert` key defined. A String value represents inserting text. A Number value represents inserting an embed, with the value corresponding to an embed type (such as an image or video).\n\nHere we will use 1 to represent images and 2 to represent videos, but your application can choose whatever mapping is convenient.\n\nIn both cases of text and embeds, an optional `attributes` key can be defined with an Object to describe additonal formatting information. Formats can be changed by the [retain](#retain) operation.\n\n```js\n// Insert a bolded \"Text\"\n{ insert: \"Text\", attributes: { bold: true } }\n\n// Insert a link\n{ insert: \"Google\", attributes: { href: 'https://www.google.com' } }\n\n// Insert an image\n{\n insert: 1,\n attributes: {\n alt: \"Lab Octocat\",\n src: 'https://octodex.github.com/images/labtocat.png'\n }\n}\n\n// Insert a video\n{\n insert: 2,\n attributes: {\n src: \"https://www.youtube.com/watch?v=dMH0bHeiRNg\",\n width: 420,\n height: 315\n }\n}\n```\n\n### Delete Operation\n\nDelete operations have a Number `delete` key defined representing the number of characters to delete. All embeds have a length of 1.\n\n```js\n// Delete the next 10 characters\n{ delete: 10 }\n```\n\n### Retain Operation\n\nRetain operations have a Number `retain` key defined representing the number of characters to keep (other libraries might use the name keep or skip). An optional `attributes` key can be defined with an Object to describe formatting changes to the character range. A value of null in the `attributes` Object represents removal of that key.\n\n*Note: It is not necessary to retain the last characters of a document as this is implied.*\n\n```js\n// Keep the next 5 characters\n{ retain: 5 }\n\n// Keep and bold the next 5 characters\n{ retain: 5, attributes: { bold: true } }\n\n// Keep and unbold the next 5 characters\n// More specifically, remove the bold key in the attributes Object\n// in the next 5 characters\n{ retain: 5, attributes: { bold: null } }\n```\n\n\n## Deltas\n\nA Delta is made up of an array of operations. Unless otherwise specified all methods are self modifying and return `this` for chainability.\n\nAll methods also maintain the property that Deltas are represented in the most compact form. For example two consecutive insert operations of plain text will be merged into one.\n\n---\n\n### constructor\n\nCreates a new Delta object.\n\n#### Methods\n\n- `new Delta()`\n- `new Delta(ops)`\n- `new Delta(delta)`\n\n#### Parameters\n\n- `ops` - Array of operations\n- `delta` - Object with an `ops` key set to an array of operations\n\n*Note: No validity/sanity check is performed when constructed with ops or delta. The new delta's internal ops array will also be assigned to ops or delta.ops without deep copying.*\n\n#### Example\n\n```js\nvar delta = new Delta([\n { insert: 'Hello World' },\n { insert: '!', attributes: { bold: true }}\n]);\n\nvar packet = JSON.stringify(delta);\n\nvar other = new Delta(JSON.parse(packet));\n\nvar chained = new Delta().insert('Hello World').insert('!', { bold: true });\n```\n\n---\n\n### insert()\n\nAppends an insert operation.\n\n#### Methods\n\n- `insert(text, attributes)`\n- `insert(embed, attributes)`\n\n#### Parameters\n\n- `text` - String representing text to insert\n- `embed` - Number representing embed type to insert\n- `attributes` - Optional attributes to apply\n\n#### Example\n\n```js\ndelta.insert('Text', { bold: true, color: '#ccc' });\ndelta.insert(1, { src: 'https://octodex.github.com/images/labtocat.png' });\n```\n\n---\n\n### delete()\n\nAppends a delete operation.\n\n#### Methods\n\n- `delete(length)`\n\n#### Parameters\n\n- `length` - Number of characters to delete\n\n#### Example\n\n```js\ndelta.delete(5);\n```\n\n---\n\n### retain()\n\nAppends a retain operation.\n\n#### Methods\n\n- `retain(length, attributes)`\n\n#### Parameters\n\n- `length` - Number of characters to retain\n- `attributes` - Optional attributes to apply\n\n#### Example\n\n```js\ndelta.retain(4).retain(5, { color: '#0c6' });\n```\n\n---\n\n### length()\n\nReturns length of Delta.\n\n#### Methods\n\n- `length()`\n\n#### Example\n\n```js\nnew Delta().insert('Hello').length(); // Returns 5\n\nnew Delta().insert('A').retain(2).delete(1) // Returns 4\n```\n\n---\n\n### slice()\n\nReturns copy of delta with subset of operations.\n\n#### Methods\n\n- `slice()`\n- `slice(start)`\n- `slice(start, end)`\n\n#### Parameters\n\n- `start` - Start index of subset, defaults to 0\n- `end` - End index of subset, defaults to rest of operations\n\n#### Example\n\n```js\nvar delta = new Delta().insert('Hello', { bold: true }).insert(' World');\n\n// {\n// ops: [\n// { insert: 'Hello', attributes: { bold: true } },\n// { insert: ' World' }\n// ]\n// }\nvar copy = delta.slice();\n\n// { ops: [{ insert: 'World' }] }\nvar world = delta.slice(6);\n\n// { ops: [{ insert: ' ' }] }\nvar space = delta.slice(5, 6);\n```\n\n---\n\n### compose()\n\nCompose with another Delta, i.e. merge the operations of another Delta. This method is self modifying.\n\n#### Methods\n\n- `compose(other)`\n\n#### Parameters\n\n- `other` - Delta to compose\n\n#### Example\n\n```js\nvar a = new Delta().insert('abc');\nvar b = new Delta().retain(1).delete(1);\n\na.compose(b); // a == new Delta().insert('ac');\n```\n\n### transform()\n\nTransform given Delta against own operations.\n\n#### Methods\n\n- `transform(other, priority)`\n- `transform(index)` - Alias for [`transformPosition`](#tranformposition)\n\n#### Parameters\n\n- `other` - Delta to transform\n- `priority` - Boolean used to break ties\n\n#### Returns\n\n- `Delta` - transformed Delta\n\n#### Example\n\n```js\nvar a = new Delta().insert('a');\nvar b = new Delta().insert('b');\n\nb = a.transform(b, true); // new Delta().retain(1).insert('b');\n```\n\n---\n\n### transformPosition()\n\nTransform an index against the delta. Useful for representing cursor/selection positions.\n\n#### Methods\n\n- `transformPosition(index)`\n\n#### Parameters\n\n- `index` - index to transform\n\n#### Returns\n\n- `Number` - transformed index\n\n#### Example\n\n```js\nvar index = 12;\nvar transformedIndex = delta.transformPosition(index);\n```\n\n\n## Documents\n\nA Delta with only insert operations can be used to represent a rich text document. This can be thought of as a Delta applied to an empty document.\n\n---\n\n### diff()\n\nCalculates the difference between two documents expressed as a Delta.\n\n#### Methods\n\n- `diff(other)`\n\n#### Parameters\n\n- `other` - Document Delta to diff against\n\n#### Returns\n\n- `Delta` - difference between the two documents\n\n#### Example\n\n```js\nvar a = new Delta().insert('Hello');\nvar b = new Delta().insert('Hello!');\n\nvar diff = a.diff(b); // { ops: [{ retain: 5 }, { insert: '!' }] }\n```\n",
