How do I remove all values that are duplicated? So only nondublicated values are left.
const sample = [["08:00",true,],["09:00",true,],["09:00",false,], ["10:00",true,]]
const newArray = [["08:00", true,], ["10:00",true,]]
Try this :
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);Try this:
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]));
