How to leave empty square brackets in a string transformed into an array in javascript?

  • 772

I have this code to pass a string to an array

let str = 'Los desarrolladores de nik son [pepe] y [pepito]';
    let arr = str.split(' ');
    console.log(arr);

This as a result gives me an array that contains each word, does anyone know how to make [pepe] and [pepito] remain inside the array with empty brackets

that instead of this:

['Los', 'desarrolladores', 'de', 'plop', 'son', '[pepe]', 'y', '[pepito]']

left this:

['Los', 'desarrolladores', 'de', 'plop', 'son', '[]', 'y', '[]']
javascript

    You can do this by substituting (with string.replaceand a regex) the names in the square brackets for empty square brackets. After the array.split. Something like:

    const sentence = 'Los desarrolladores de nik son [pepe] y [pepito]';
const sentenceWithoutNames = sentence.replace(/\[.*?\]/g, '[]');
const sentenceWords = sentenceWithoutNames.split(' ');

console.log(sentenceWords);
