I'm trying to use array.find() to get the first JSON string that contains amogus. I've tried to read the JSON file using fs then using JSON.parse() to make it readable. However, I can't seem to get it to do what I want it to do.
JSON file:
{stuff: ["hosds29083", "amogus1208", "amogus1213"]
desired output: amogus1208
Thanks.

Here is a possible solution:
const json = JSON.parse(data);
const first = json.stuff.find(obj => obj.includes("your string"))

const foundString = yourParsedJsonObject.stuff.find(string => string.includes("amogus"))

const json = `{
"stuff": ["hosds29083", "amogus1208", "amogus1213"]
}`
const data = JSON.parse(json)
const findData = data.stuff.find(s=>s.includes("amogus"))
console.log(findData)

I'm trying to return a Boolean value based on truthy of a given condition from an arrow function. The code is look like following
checkIsBasicInformationCompleted() {
const info = this.basicInformation;
const valid = () => {return !!(info.firstName && info.lastName && info.email && info.phone);};
console.log(valid);
},
But here instead of returning true/false, this function is printing itself. Can anybody explain the thing running here ? And how can I get a true/false value here ?
Fiddle sample: https://jsfiddle.net/tebz4Lc3/

You are printing a reference to the function here, use console.log( valid() ) to actually execute the function and print the return value.

console.log(valid());
This is how the logging should be.

I am new to programming in general. Currently learning about Javascript, node.js, and express...
const app = express();
const path = require('path');
Why does app.use(express.static(path.join(...))); works while app.use(app.static(path.join(...))); does not work?
Aren't they the same thing?

Aren't they the same thing?
No.
The return value of a function is not the same thing as the function.
What does it mean when I assign a function to a variable? const app = express()
You are not assigning a function to a variable. You are assigning the return value of a function to a variable.
function add(a, b) { return a + b };
const assignAFunction = add;
const assignTheReturnValue = add(1,1);
console.log({ assignAFunction, assignTheReturnValue });

i am trying to set value in asyn buttonHander function. it's working fine in onSortedViewHandler function but when i try to console.log array value in render arrayis empty, i don't know why but it's not rendering
state = { inputText: "", sortedArrayList: [] };
onSortedViewHandler = async () => {
const data = await this.props.sortedContract.methods
.sortNumberArrayList()
.call()
.then((array) => {});
this.setState({ sortNumberArrayList: data }); // array output is correct here
console.log(data);
console.log(this.state.sortNumberArrayList); // array output is correct here
};
it's working fine in this funtion,
but not array show empty in render
render() {
console.log(this.state.sortedArrayList); //but empty here
}
``

render() {
console.log(this.state.sortNumberArrayList);
}
This should render you the correct one. You had different naming state.

Please tell me how can i access the nested objects in arrays
I have pasted the code below and I want to access the nested objects using
only through map function.
Data=[
{name:'Amir'},
{name:'jamile'},
{name:'hali'}
]
const result=Data.name.map( (name) => name);
console.log(result);

You can do it either by accessing the property using . operator or by destructing.
let Data=[
{name:'Amir'},
{name:'jamile'},
{name:'hali'}
]
const result=Data.map( ({name}) => name);
console.log(result);
const result2=Data.map( (name) => name.name );
console.log(result2);
