Inverting if condition with boolean

More of a curiosity than anything. I currently have a piece of code that looks like this: 

var inputsArray=[];
userInputs.forEach(input=>{
        if(isInvert ? query.name == input.name : query.name != input.name){
              inputsArray.push(input.id);
        }
    });

Before that i had: 

            var inputsArray=[];
            userInputs.forEach(input=>{
               if(isInvert){
                    if (query.name == input.name){
                       inputsArray.push(input.id);
                    }
              }else {
                   if (query.name != input.name){
                      inputsArray.push(input.id);
                    }
              }
          });

Essentially when isInvert is true the opposite values are going to be stored to when isInverse is false. I'm wondering if there is an even better way to write the first snippet of code?

you can use this if(isInvert ^ (query.name != input.name)) inputsArray.push(input.id); wher ^ is the XOR operation

You can further simplify to

if (isInvert == (query.name == input.name)) {
    inputsArray.push(input.id);
}
