Parece besteirinha, essa lógica, mas fez eu raciocinar e estudar um pouco.

Nao sei se é o melhor script, mas funciona bem!

    let list = this.shuffleArray(this.state.list) //embaralha o array
    let amigos = [...list];
    let count = 0;

    while(amigos.length > 0){

      let participante = this.state.list[count];
      var index = Math.floor(Math.random() * amigos.length); 
      let amigo = amigos.find((amigo, i) => {
        return i === index && amigo.name !== participante.name;
      });

      if(amigo){
        participante.amigo = amigo.name;
        amigos.splice(index, 1); //retiro o amigo da lista pra nao ser escolhido novamente
        count++;
      }
    }

Imagina a seguinte situacao...

Voce tem uma frase e quer montar um objeto com essa frase...Exemplo

var frase = 'Minha frase';

e quer que o objeto fique

obj = { M : 1, i : 2, n: 3, h: 4, a: 5 }

seria simples neh...só percorrer o frase e inserido valor.

var obj = {};
var arr  = [];
"fraseeeeeeee".split("").forEach((letra, index) => {
obj[letra] = (obj[letra]) ? obj[letra]+=1 : 1;
})
Object.keys(obj).forEach(letra => {
arr.push({
letra: obj[letra]
})
})
console.log(arr)

sabe oque isso vai fazer? vai gerar um array

1. 0: {letra: 1}
2. 1: {letra: 1}
3. 2: {letra: 1}
4. 3: {letra: 1}
5. 4: {letra: 8}

mas se a gente fizer uma alteracaozinha aqui...

arr.push({
[letra]: obj[letra]
})

olha como fica:

1. 0: {f: 1}
2. 1: {r: 1}
3. 2: {a: 1}
4. 3: {s: 1}
5. 4: {e: 8}

Espero que sirva essa dica!

var array = [1,1,1,1,1,1,1,1,22,2,2,2,2,2,2,2,3,3,3,3,4,4,4,4,4,444]
array.filter((x, i, a) => a.indexOf(x) == i).length

espero que sirva!
