How I can do that simply ? I just want use methods contained in allPersos.(..), here methodsNames is not iterable.

var actualPerso = getPersoByName(selectPerso.value, allPersos);
    var targetPerso = getPersoByName(selectTarget.value, allPersos);
    var methodsNames = Object.getPrototypeOf(actualPerso);
    var propertyNames = Object.getOwnPropertyNames(actualPerso);
    if (!actualPerso || !targetPerso || !methodsNames || !propertyNames)
        return;
    
    var valueProperties = [];

    propertyNames.forEach( (propertyName) => {
        valueProperties.push(actualPerso[propertyName]);
    });

    for (var method of methodsNames){
        if (method.name === selectAttaque.value){
            actualPerso.method(targetPerso);
        }
    }
