Kind: static method of _
Returns: boolean - Returns true based on the result of _.includes

| Param | Type | Description | | --- | --- | --- | | collection | array | object | string | The collection to search | | values | mixed | The value or values to search for | | fromIndex | number | The index to search from. |

Example

_.includesAll( [1,2,3], [1,3] )
 // => true
 _.includesAll( [1,2,3], [1,2], 2 )
 // => false
 _.includesAll( {user: 'fred', age: 40 }, ['fred', 40] )
 // => true
 _.includesAll( 'abcdef', ['a','d] )
 // => true

_.levenshtein(strA, strB) ⇒ number

Use the Levenshtein formula to calculate the distance in the similarities of two separate strings, which can be anywhere from 0 (strings are identical) to the length of the longer string provided (100% different). The higher the distance, the more different the strings are, but the distance can only be as high as high as the number of characters in the longer string

Kind: static method of _
Returns: number - Levenshtein distance value
Note: ALPHA PHASE - Under Construction

• [ ] Create unit tests

| Param | Type | Description | | --- | --- | --- | | strA | string | number | String A | | strB | string | number | String .... Yep, B |

Example

levenshtein( 'foo','foo' )
 // => 0
 levenshtein( 'foo','bar' ) 
 // => 3

_.strDist(strA, strB) ⇒ number

String Difference Distance (In percentages). This basically returns the Levenshtein value as a percentage

Kind: static method of _
Returns: number - Levenshtein distance percentage (WITHOUT the % on the end)
Todo

• [ ] Create unit tests

| Param | Type | Description | | --- | --- | --- | | strA | string | number | String A | | strB | string | number | String .... Yep, B |

Example

strDist( 'foo','foo' )
 // => 0
 strDist( 'foo','bar' ) 
 // => 100
 strDist( 'something', 'somewhere' )
 // => 44.44

_.plural(str) ⇒ string

Return the plural version of a string

Kind: static method of _
Returns: string - Plural version of same noun
Todo

• [ ] Create unit tests

| Param | Type | Description | | --- | --- | --- | | str | string | Singular format of a noun |

Example

_.plural( 'apple' )
 // => apples
 _.plural( 'toy' )
 // => toys
 _.plural( 'fly' )
 // => flies

_.mergeObjs([...sources]) ⇒ object

Merge multiple objects together without mutating the original object This basically just hands everything off to _.merge, just adds an empty object to the beginning, so _.merge( {}, ObjsA, ObjsB ) would be the same as _.mergeObjs( ObjsA, ObjsB )

Kind: static method of _
Returns: object - Newly merged object

| Param | Type | Description | | --- | --- | --- | | [...sources] | object | The source objects |

Example

_.mergeObjs( { a: 1 }, { b: 2 }, { c: 3 } )
 // => { a: 1, b: 2, c: 3 }

_.setException(item, [type]) ⇒ Mixed

Ensures the item is an instance of the exception specified by type

Kind: static method of _
Returns: Mixed - Returns an instance of Error, or whatevers specified by item

| Param | Type | Default | Description | | --- | --- | --- | --- | | item | Mixed | | Item/Error/Whatever | | [type] | Mixed | Error | Exception type (Default: Error) |

Example

let err = 'Error Str'
 // => Error Str
 err = _.setException( err )
 // => [Error: Error Str]
 err = _.setException( err )
 // => [Error: Error Str]
 // Notice no matter how many times its used, Error is not nested, as opposed to setting new Error( err )

_.pullSample(arr) ⇒ Mixed

Pulls a sample from an array - Useful for when iterating over an array (manually), and having to remove the previous iterations

Kind: static method of _
Returns: Mixed - Whatever element was sampled from the array
Note: This method mutates the array, just as _.pull does

| Param | Type | Description | | --- | --- | --- | | arr | array | Array to sample |

Example

var data = [ 100, 200 ]
 _.pullSample( data )  
 // => 200                   
 _.pullSample( data )  
 // => 100           
 _.pullSample( data )
 // => []

_.pullSampleSize(arr, size) ⇒ array

Pulls an array of samples from an array - Basically the same thing as _.pullSample, except this samples multiple elements, with the amount specified by the size parameter

Kind: static method of _
Returns: array - Array of one or more elements from arr
Note: This method mutates the array, just as _.pull does

| Param | Type | Description | | --- | --- | --- | | arr | array | Array to sample | | size | number | Amount of elements to sample/remove from arr |

Example

var data = [ 100, 200, 300, 400 ]
 _.pullSampleSize( data, 2 )  // [ 100, 200 ]
 _.pullSampleSize( data, 2 )  // [ 300, 400 ]
 _.pullSampleSize( data, 2 )  // [ ]
 data                           // []

_.validPattern(pattern, flags, reason) ⇒ boolean | string

Validation for legitimate regular expression pattern validation

Kind: static method of _
Returns: boolean | string - If the pattern will work in a regexp check, then true
Note: This is best used when validating strings, as invalid regexp elements will throw an error before this function even gets a chance to validate. Meaning something like _.validPattern(/a/asdf) will throw an exception on the line the invalid pattern was passed
Todo

• [ ] Somehow parse a string for a regex pattern and flags; EG: /foo/g -> ['foo','g']; %bar%i -> ['bar','i']

| Param | Type | Description | | --- | --- | --- | | pattern | Mixed | Pattern to validate (String, number, regexp, etc) | | flags | string | Regular expression flags (Not required) | | reason | boolean | If pattern is invalid, instead of returning false, return the error (string), which would change the return to true = valid, and any string = invalid |

_.typeof(value, inspect, returnTypes, flaggedVals) ⇒ string

Return the type of a specific variable, much like the standard 'typeof', only with a little more functionality. This is primarily used for input from libraries/packages/modules that may convert the variable to a different type when interacting with it. For example, pretty much anything passed through the URI parameters will be a string, as well as anything passed through GetOpts, but you may want integers, for example, to actually be identified as numbers, or true/false/null/undefined strings to be identified as boolean/null/undefined. That's what the scrutinize parameter does here, it will process the variable to attempt to identify the type it originally was.

NOTE: If no type is matched, then the toString() value will be returned

Kind: static method of _
Returns: string - The variable type; The default type names are: undefined, null, string, boolean, array, element, date, regexp, object, number, function, unknown However, these can be overridden by providing an object as the 3rd parameter

| Param | Type | Description | | --- | --- | --- | | value | * | Value to process | | inspect | boolean | Determine if the true value type should be determined through logical processing | | returnTypes | object | Object of return type strings to overwrite | | flaggedVals | object | Values used to determine the real value types of flagged values (Only used if scrutinize is enabled) |

Example

_.typeof( [1,2] )       // array
         _.typeof( 'foo' )       // string
         _.typeof( true )        // boolean
         _.typeof( 'true' )      // string
         _.typeof( 'true',true ) // boolean
         _.typeof( null )        // null
         _.typeof( 'null' )      // string
         _.typeof( 'null',true ) // null
