v-on:click="selectedPost = post" is the culprit; selectedPost is a prop here and you cannot assign to a prop.

There are two different solutions depending on what you want:

1. Make selectedPost a local data property instead of a prop. You can then modify selectedPost but since it is no longer a prop, you cannot accept selectedPost from the parent anymore (but you're not really doing that anyway).

That one does not work?

first of all as aerial301 said you are not targeting the img tag but the div tag.

secondly you should change the html from

You should not destructure your context, you're simply assigning an array to it, so it's just

const reviews = useGlobalContext()

Also it's always good idea to assign some initial context values so you can debug things like that more precisely or further implement some logic for placeholders etc.

There are several problems in your code.

First you have to provide a function as a parameter of window.addEventListener. You are currently passing the return value of the function after it has executed, which is not want you want:

The input element is inside hidden element. You need to unhide the parent element first:

You are almost there, but you forgot to remove display: flex on responsive view changing it into display:block will fix your problem

You don't have to worry about do-while conditions or breaks. You can keep generating your random number with a simple while loop and compare the generated number against oldRand, if they are different return newRand.

To process 100 million lines at once you would have to have 100 million threads. Another approach to improve the speed of your code is to split the work among different threads (lower than 100 million).
Because write and read operations from file are not asynchronous, you would be better off with reading all the file at the beginning of your program and write out thr processed data at the end. In the code below i will assume you do not care about the order at which wou write the file out. But if order is important you could set a dictionary that has as key the positional value of the current line being elaborated by a specific thread and at the end sort accordingly.
