Is there a possible way to parse a string with breaklines to an object using JSON.parse?
const text = '{ "name": "Anne", "desc": "Hi,\nThis is me" }';
const obj = JSON.parse(text);
console.log(obj);

There are two things here:
To answer your question, you simply need to escape the character like this:
"Hi,\\nThis is me"
For your code specifically, you also have another syntax error with a ,, instead of a ::
const text = '{ "name": "Anne", "desc": "Hi,\\nThis is me" }';
const obj = JSON.parse(text);
console.log(obj);
output:
{
name: "Anne" ,
desc: "Hi, This is me"
}

I wanted to interpolate variables in strings in JS so I used ``(backticks) as shown here -
How To Interpolate Variables In String in JS
Then, I Wanted To put IF-Statements in jQuery Append So I got this -
IF Statements In jQuery Append
But When I use Both Together , Backticks Don't Output Text As Usual-
$("main").append(`Hello ${my_var}`+(second_var>1?"hi ":"bye")+`Bye ${my_var})`
This Results Only In "hi" , The Backticks Before And After The Ternary Operator Don't Output Anything.
HELP ??
You can do something like the below.
const my_var = "Name";
const seconde_var = 2;
console.log(`Hello ${my_var} ${seconde_var >1 ? "hi": "bye"} bye ${my_var}`);

I'm trying to get JSON in a valid format so that it can be sent to an API and I can't figure out why the below JSON is not valid. Please can someone explain why this is not valid?
{
"Description": "test",
"Quantity": "0.30",
"UnitAmount": "6400.0",
"TaxType": "OUTPUT2",
"AccountCode": "200"
},
{
"Description": "test2",
"Quantity": "0.30",
"UnitAmount": "0.0",
"TaxType": "OUTPUT2",
"AccountCode": "200"
}
The top level of a JSON text must be one of the JSON data types (like object, array, or string).
There can only be one data type at the top level.
You have an object but then you have a comma and then a second object.
Perhaps you should wrap it in an array.

const data = [{
"detectedLanguage": {
"language": "hi",
"score": 1
},
"translations": [{
"text": "long steff",
"to": "en"
}]
}]
How do I console.log only the translation.text field?
I tried console.log(JSON.stringify(res.data.translation.text) but that gives me the following error:
TypeError: Cannot read property 'text' of undefined
Try this,
console.log(data[0].translations[0].text)
No need to use Json.stringify, because data[0].translations[0].text is not a Json, it is a string.
You created arrays and am missing the index and the "s" in translations:
console.log(JSON.stringify(data[0].translations[0].text))
I also don't know why you're referencing it as res.data

I've was given this is a multiple choice JS question. I said [], I just wanted to check if this is correct and if not why?
Consider this if statement:
if (loggedIn) {
body_classes = ["user-active"];
}
Which pair of characters in this code is optional?
""
()
{}
[]
The optional characters are the braces {}
if (loggedIn) {
body_classes = ["user-active"];
}
is the same as
if (loggedIn)
body_classes = ["user-active"];
If you remove the square brackets then body_classes becomes a string rather than an array.

I've used this :
String.Prototype.left = function left(count){
return this.substr(0,count);
}
And apply it this way :
var string = "Hello Stack!";
console.log(string.left(5));
And the console tells me :
TypeError: example.left is not a function
console.log(example.left(5));
How can I fix it? And where is the problem?
String.prototype.left = function(index){
return this.substring(0,index);
}
var str = "Hello World";
console.log(str.left(5));
