Documentation

The following functions are currently implemented:

• assertArraysEqual(a , b): taking two arrays and return passed if it is equal and failed otherwise.
• assertEqual(a,b): return passed if it is equal and failed otherwise.
• assertObjectEqual(a,b): taking two objects and return passed if it is equal and failed otherwise.
• countLetters(a): taking string and return object with numbers of occurrence of each letter.
• countOnly(a,b): taking an array "a" and object "b" and return object with numbers of occurrence of each item in array.
• eqArray(a,b): taking two arrays and return true if those are equal.
• eqObject(a,b): taking two objects and return true if those are equal.
• findKey(a,b): takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value.
• head(a): take an array and return the first item in array.
• letterPositions(a): taking a string and return an object with numbers of occurrence of each letter in the string.
• map(a , b): taking an array and a callback function and return a new array based on the results of the callback function.
• map(a , b): taking an array with the middle item of first array if it's length is odd and mean of two middle items if the length is even.
