const _ = require('@kennethz374f/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
head(Array)
: it only show the first element of the array.tail(Array)
: it slices out the first element of the arraymiddle(Array)
: get the middle element in a array; if array length is even, it will return the middle two element of the array. if the array length is odd it will return the middle element of the array;if the array length is less than 2, it will return undefined,assertArraysEqual(actualArr,ExpectedArr)
: comparing whehter the acutal array and the expected array are identical, then print out a pass or fail message.eqArrays(Array1, Array2)
: comparing whether two arrays are identicalassertEqual(actual, expected)
: comparing whether the actual value and the expected value are identical,then print out a pass or fail message.countLetters(String)
: count the total appearance of each letter and return an object with letter : times of occurance.countOnly(obj1, obj2)
: obj1 is the source and obj2 are the items that you want to count. it will return an object contains item name and numbe of its occurance;eqObjects(obj1,obj2)
: to determine whether two objects are identicalfindKey(obj1,callback)
: figure out the property name, can use callback to modified conditionfindKeyByValue(obj,value)
: figure out the property name, given the value of propertyflatten(Array)
: an array with other arrays inside, it can flatten it into a single-level array.letterPositions(String)
: when enter a string, it will return an object that shows the positon of each lettermap(array,calback)
: map will loop through each element of the array and make modification with the callback function.takeUntil(array,callback)
: takeUntil will keep collecting items from a provided array until the callback provided returns a truthy value.without(ArrOfSrc,ArrOfRemove)
: This function should take in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove arrayassertObjectsEqual(actualObj,ExpectedObj)
: compare whether the acutal object and the expected object are identical, then print out a pass or fail message.
