I'm new to coding and trying to figure out nested javascript functions. I've searched other questions but still can't figure it out. I'd like a function that takes a string of numbers seperated by spaces, converts the string to an array, and then outputs the result of a mathematical function on the array.
I've written something using the following outline and it works, but seems messy and don't know that I am really doing it the best way. I don't really understand how to call a function from another function.
function doMathOnThisString(string) {
var ar = convertStringToArray(string);
return doMathOnArray(ar);
function convertStringToArray(string) {
//code that converts the original input string to an array
return (ar)
};
function doMathOnArray(a) {
//code that does math on an array
};
}
You're doing just fine with what you have, just take it a step further and you'd be fine. Kindly see my solution below:
function doMathOnThisString(string) {
// Converts a string of numbers separated by spaces to an array
function convertStringToArray(input) {
return input.split(' '); // split input on spaces
};
// Sums up the value in the array of number string
function doMathOnArray(numbersString) {
return numbersString
.map((number) => Number(number)) // Convert each (string) number to a proper number
.reduce((acc, curr) => acc + curr); // Add each number
};
var stringNumberArray = convertStringToArray(string);
return doMathOnArray(stringNumberArray);
}
const result = doMathOnThisString('1 2 3 4 5 6 7 8');
console.log(result);Collected from the Internet
