JavaScript function changes value of local storage

Question

I am creating a website where when different functions occur in javaScript, I need to change the value of my local storage. For example here is my current code:

localStorage.setItem('colorvar', '#EBDBC2');

I need to create something where when a function occurs, the value which currently it set to #EBDBC2 will change to a value of my choice. I've tried just duplicating the line of code above and putting it in a function and changing the value but for some reason that wasn't working. Does anybody know how I can create a function where when the function runs, it will change the value in my local storage?

Are you sure the function is running? Try adding a console.log to the function. — Bud Linville

Please see stackoverflow.com/help/how-to-ask, then revise your post with your attempt. Just asking for some code will surely get your question closed by the community. — isherwood

You can do it like this:

const setLocalStorageValue = (new_value) => localStorage.setItem('colorvar', new_value);
const getLocalStorageValue = () => localStorage.getItem('colorvar');

setLocalStorageValue('Value_1');
console.log(getLocalStorageValue());
setLocalStorageValue('Value_2');
console.log(getLocalStorageValue());

Here is the working example: https://jsfiddle.net/5af4e6ks/15/
