Return to incorrect IF condition

Question

I make a request in the api to get some data, and then I foreach and give the result for a variable this.DadosQueTaNaTela soon after I make another request in another api to take the data and do a foreach and the result I give to this.OlhaDadosDaApiJson and I need to create foreach inside foreach pq it does not give the expected result.

The data that comes in the two variables are strings. Ex.: this.DadosQueTaNaTela = 15 and this.OlhaDadosDaApiJson = 15

With this I make an if condition:

        this.grav.forEach(variable => {
            this.OlhaDadosDaApiJson = variable
            if (this.DadosQueTaNaTela.FI == this.OlhaDadosDaApiJson.FI) {
                console.log('Dados iguais')
                console.log(this.DadosQueTaNaTela.FI)
            }else{
              console.log('Dados diferentes')
              console.log(this.DadosQueTaNaTela.FI)
            }
        })

The data I am comparing are equal, IE, should only show on the console the message "Same data", but shows on the console everything that is on Else also.

Does anyone know why this problem?

Note: I will put the full code that comes before the if to get a better sense

this.MetaService.FiliaisMetaDiarias().subscribe(
  data => {
    const response = (data as any)
    this.objeto_retorno = JSON.parse(response._body);

    this.fil.length = 0
    this.filMetade.length = 0
    this.filNaoAtingida.length = 0


    this.objeto_retorno.forEach(element => {

      this.tots = element.TOTAL
      element.TOTAL = (element.TOTAL * 100).toFixed(3) + '%'
      element.TOTAL = element.TOTAL.toString().replace(".", ",")

      if (this.tots >= this.MetaAtingida) {

        this.fil.push({
          FI: element.FILIAL,
          porc: element.TOTAL
        });

        this.mainColor = 'MetaAtingida'

        this.fil.forEach(element => {
          this.DadosQueTaNaTela = element
        })

        this.MetaService.CheckOrderGet().subscribe(
          data => {
            const response = (data as any)
            this.obj = JSON.parse(response._body)

            this.obj.forEach(element => {
              this.grav = element
            })


          }, error => {
            console.log('error')
            console.log(error)
          }

        )

RESULT THAT APPEARS ON THE CONSOLE BEFORE IF

The value 36 is what you see in the two API’s

IF VALUE

Answer 1

let array:any[] = [];

let exist:boolean = false;

this.DadosQueTaNaTela.forEach(apielement => {

  var api = apielement;
  existe = false;
  this.OlhaDadosDaApiJson.forEach(dadoselement => {

      var dados = dadoselement;

      if (!exite){

        if (dados == api){
            existe = true;
            array.push(dados);
        }

      }

  }
}

Now this method only finds if it has some equal value in the second vector ... if you want to save the value or something would have to implement another logic.
