I need to do one to check if inside my array this.variacaoForm.value.variacoes has a sku like the other, I tried something like:

for(let i=0;i<this.variacaoForm.value.variacoes.length;i++){
  for(let j=i+1;j<this.variacaoForm.value.variacoes.length;j++){
    if(this.variacaoForm.value.variacoes[i].sku == this.variacaoForm.value.variacoes[j].sku){
      console.log('possui sku iguais')
    }
  }
}

In my console.log is returning the message more than once when you have equal sku

I also tried to:

for(let i=0;i<this.variacaoForm.value.variacoes.length;i++){
  for(let j=0;j<this.variacaoForm.value.variacoes.length - 1;j++){
    if(this.variacaoForm.value.variacoes[j].sku == this.variacaoForm.value.variacoes[j+1].sku){
      console.log('sku iguasi')
    }
  }
}

    utilize === (3 equal signs) in javascript. So it checks if the variable types are also equal. The == check whether the values, both string or number, are similar.

    I don’t know what your array looks like, but it’s no longer simple to use a filter() that uses a function that checks whether the array contains elements more than once?

    And what would be the expected result?

It would be more interesting to use the method filter or map to traverse the two arrays, try to use this way.

this.variacaoForm.filter((value,index) => {
    return value.vairacoes.sku === this.variacaoForm.value.variacoes[index].sku });
