API

When starting calculator, it starts a node repl with all of the following properties set as properties of the GLOBAL object. All Math properties are replaced with Math.(prop) so you can write var f = func('f(x) = sin(x)') instead of var f = func('f(x) = Math.sin(x)')

func

for sum of array elements

const sumOfArray = (a) => a.reduce((a,b)=>a + b, 0);

for sort of array elements

const sortedArray = (a) => a.sort();

for remove duplicates from elements

const removeDuplicates = (arr) => { return arr.filter((item, index) => arr.indexOf(item) === index); // return ...new Set(arr) }
