¿Cómo elimino todos los valores que están duplicados? Entonces solo quedan valores no duplicados.
const sample = [["08:00",true,],["09:00",true,],["09:00",false,], ["10:00",true,]] const newArray = [["08:00", true,], ["10:00",true,]]Prueba esto :
const sample = [["08:00",true,],["09:00",true,],["09:00",false,], ["10:00",true,]]; const flatArr = sample.flat(); const res = sample.filter((arr, index) => flatArr.indexOf(arr[0]) === flatArr.lastIndexOf(arr[0])); console.log(res);Prueba esto:
const sample = [ ["08:00",true,], ["09:00",true,], ["09:00",false,], ["10:00",true,] ]; const newArray = [ ["08:00", true,], ["10:00", true,] ]; function checkDuplicate (array) { let output = []; array.forEach(function(item) { if(!JSON.stringify(output).includes(JSON.stringify(item))){ output.push(item); } }); return output; } console.log(checkDuplicate([...sample,...newArray]));
