newArr = "arr = [1, 2, 3]"Currently, I have an array stored in a variable as shown below:
arr = [1, 2, 3]
Is there a way to convert this array statement into a string like this?
newArr = "arr = [1, 2, 3]"Here is a helpful code snippet:
const arr = [1, 2, 3];
const str = `${Object.keys({arr})} = ${JSON.stringify(arr)}`;
console.log(str);For more information, you can refer to these resources:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify
When dealing with data formatting in JavaScript, I often rely on the JSON.Stringify() method.

If taken in its literal sense, you could achieve this:
let numbersArray = [5, 10, 15];
let newNumbersArr = `numbersArray = [` + numbersArray.join(',') + "]";
const newArr = `arr = [${JSON.stringify(arr)}]`;
One way to approach this is by converting it into a function and then calling the function using declaration.
const createArray = () => {
arr = [1, 2, 3]
}
const stringifiedFunction = createArray.toString()
newArr = stringifiedFunction.slice(9, stringifiedFunction.length).slice(0, stringifiedFunction.length - 1)
The above code converts the function into a string using .toString() which results in '() => {\n arr = [1,2,3]}'. We then use .slice method to remove unnecessary parts of the string.
Why not give this a shot:
let numbers = [4, 5, 6];
const newNumbers = `numbers = [${numbers.toString()}]`;
console.log(newNumbers);
//For a more versatile approach:
console.log(`${Object.keys({numbers})} = [${numbers.toString()}]`);https://i.stack.imgur.com/3GSft.jpgMy application abruptly terminates with the error message "killed" without providing any additional information or stack trace.
