In order to display an array element through 'filter' in JavaScript, you need to use the filter() method, which creates a new array with all elements that pass the test implemented by the provided function.
Here's an example:
const arr = [1, 2, 3, 4, 5];
const filteredArr = arr.filter(element => element === 3);
console.log(filteredArr); // Output: [3]
In this example, we have an array arr
containing the numbers 1 through 5. We use the filter()
method to create a new array called filteredArr
consisting of only the element that matches the condition element === 3
.
The output of console.log(filteredArr)
will be [3]
, as expected.
