employing the join method with a property of an object

After trying to modify my nested array by using the join method and adding a line break with \n, I encountered an issue:

const exampleArray = [["Hello"], ["world"], ["example"]]
    .map((el) => el)
    .join("\n");

Initially, everything worked as expected and I achieved the desired output:

Hello

world

example

However, when attempting to include this exampleArray within an object's value, the \n characters were displayed instead of creating line breaks.

This was my approach:

const theObj = {
    value: exampleArray,
  };

The resulting output showed:

Object { value: "Hello\nworld\nexample" }

To address this issue and have line breaks in the value, I need to identify what caused the problem and find a solution.

Answer №1

The issue arises from using objects to store data in the format of {key : string} and {value : }. It is not possible to include visual line breaks in object-values. However, if you print Object.value instead of the Object itself, the data will be displayed with visual line breaks.

const obj = {
  value : 'Hindi\nEnglish\nFrance'
}
console.log(obj)
console.log(obj.value);


/* The first one will output - {
  "value": "Hindi\nEnglish\nFrance"
} */

/* The second one will output 
Hindi
English
France */

Answer №2

When displaying text that contains line breaks, the value will appear as expected when viewed in the console by calling theObj.value.
