I want to create a comma-separated list of items within an array.
For example:
[
{value: 1, text: 'one},
{value: 2, text: 'two},
{value: 3, text: 'three},
{value: 4, text: 'four},
]
I considered using Array.join (https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Array/join) - but this doesn't work with arrays containing more complex data, resulting in [object Object].
How can I extract and concatenate the values to achieve an output of one, two, three, four?
To retrieve the text property from each element in your array and then concatenate them with a desired separator, you should use the map method.
const arr = [
{value: 1, text: 'one'},
{value: 2, text: 'two'},
{value: 3, text: 'three'},
{value: 4, text: 'four'}
];
const output = arr.map(el => el.text).join(', ');
console.log(output);Discovered the remedy:
{{list.forEach(item => item.name).join(', ')}}
