Why this JavaScript doesn't translate words from input, please help me.

Answer 1

1. input_text should be the source, not the target
2. Iterate through the words, not the dictionary.

Here is how to get the items:
for(let index in arr) {
let item = arr[index];
// do something with the item
}

in your case something like:
for(let index in inputWords) {
let word = inputWords[index];
// do something with the word
}

For the lookup in the dictionary:
let value = dict[key]
In your case something like:
let translation = englishToFrench[word]

Answer 2

I made explanations and fixes right in the code – see the comments in the JS tab.

I think you tried to get input text from the wrong element and your iteration of the dictionary didn't work.
