Documentation
The following functions are currently implemented:
head(array)
: Retrieves the first element of an array.tail(array)
: Retrieves every element of an array after the first.middle(array)
: Retrieves the middle number(s) of an array.countOnly(array, object)
: Given an array and an object, it will return an object containing counts of everything that the input object listed as having a value of "true" (e.g. {x: true, y: false, z: true} will return a count of the occurances of x and z in the array).countLetters(string)
: Given a string, it will return an object listing each letter that occurs within the string along with the number of occurances.findKey(object, callback)
: Takes in an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.findKeyByValue(object, value)
: Takes in an object and a value and returns the first key which contains that value.flatten(array)
: Given an array with other arrays inside, it can flatten it into a single-level array.letterPositions(string)
: Returns all the indices in the string where each character is found.map(array, callback)
: Takes an array and a callback function and returns a new array based on the callback function.takeUntil(array, callback)
: Given an array and a callback function, it will iterate through that array, returning a slice containing each item iterated through until the callback function returns true.without(array, exclusions)
: Given an array, and an array of exclusions, returns a subset of the initial, removing unwanted values.
