3-to-pounds.js

// In Sprint-1, there is a program written in interpret/to-pounds.js

// You will need to take this code and turn it into a reusable block of code.
// You will need to declare a function called toPounds with an appropriately named parameter.

// You should call this function a number of times to check it works for different inputs

//Rewrite this code
    // const penceString = "399p";

    // const penceStringWithoutTrailingP = penceString.substring(
    // 0,
    // penceString.length - 1
    // );

    // const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0");
    // const pounds = paddedPenceNumberString.substring(
    // 0,
    // paddedPenceNumberString.length - 2
    // );

    // const pence = paddedPenceNumberString
    // .substring(paddedPenceNumberString.length - 2)
    // .padEnd(2, "0");

    // console.log(`£${pounds}.${pence}`);

    //Updated code to make it re-useable:

    function toPounds(fromPenceString) {
        const penceString = fromPenceString.substring(0, fromPenceString.length -1);
        const paddedString = penceString.padStart(3, "0");
        const pounds = paddedString.substring(0, paddedString.length -2);
        const pence = paddedString.substring(paddedString.length -2).padEnd(2, "0");
        return `£${pounds}.${pence}`;
    }
    console.log(toPounds("399p")); // £3.99
    console.log(toPounds("45p")); // £0.45
    console.log(toPounds("1295p")); // £12.95
    console.log(toPounds("5p")); // £0.05
