I like to use the Set Object with Spread Operator to display non-repeat data into Array:
const arr = [1, 2, 3, 1, 2, 3];
const newArr = [...new Set(arr)]; // [1, 2, 3]
Spread is a awesome feature.
Congratulations for the post!
Was going to leave the same comment :)
Note that this only works if you have an array of primitive types
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
