Make the if statement easier - Angular

Would you like to know a more efficient way to streamline this If statement? The variables are all strings and are reused in both conditions, but the outcome varies depending on whether it returns true or false.

if(params.province && !params.streetType && !params.streetNr){
  this.localityIdCP = params.localityId;
}

if(params.province && params.streetType && !params.streetNr){
  this.streetIdCP = params.localityId;
}

Answer №1

Consider using this approach:

if(params.province && !params.streetNr){
  if(params.streetType) {
    this.streetIdCP = params.localityId;
  }else {
    this.localityIdCP = params.localityId;
  }
}

Answer №2

Consider incorporating the ternary operator within an if statement for more concise code.

if(params.province && !params.streetNr){
  params.streetType ? this.streetIdCP = params.localityId : this.localityIdCP = params.localityId;
}

Answer №3

Determine the mandate values and store the outcome in a temporary variable, which will be utilized in a subsequent section where code repetition is needed

const _temp = (params.province && !params.streetNr);
this.localityIdCP = _temp && !params.streetType && params.localityId;
this.streetIdCP = _temp && params.streetType && params.localityId;
