Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual: gives highly visible feedback when passed 2 arrays, about whether they are equal or not. -
assertEqual: gives highly visible feedback when passed pieces of primitive data, about whether they are equal or not. -
assertObjectsEqual: gives highly visible feedback when passed pieces of object data about whether they are equal or not. -
countLetters: counts the non-space characters of a string passed as an argument. -
countOnly: counts how many times a certain piece of data appears in an array -
eqArrays: returns true or false when passed 2 arrays, based on whether they are equal -
eqObjects: returns true or false when passed 2 objects, based on whether they are equal -
findKey: returns the key of an object based on the result of a callback function -
findKeyByValue: returns the key of an object based on the value -
flatten: returns a flattened version of nested arrays -
head: returns the first index of an array -
letterPositions: takes 2 arguments of strings, one sentence and one letter. returns the position of the letter in the sentence. -
map: takes an array argument and a callback function, returns a new array based on the evaluation of the callback function on each item. -
middle: returns the one (if odd) or 2 (if even) middle indeces of an array -
tail: returns all but the first index in an array -
takeUntil: takes an array argument and a callback function, executes the callback on each item in the array and returns a new array consisting of every item up until the point at which the callback funcion evalutated to true. -
