why is JHipster JDL only generating strings values for Enum expressions for angular/typescript code?

Question

Not sure if this is a bug in JDL, or if I'm just not understanding it, but if I create an enum in Jhipster JDL like this

enum PricingModel {
    AVAILABILITY,   
    DEADLINES,     
    PAYMENTS        
}

Then it will generate this typescript for my angular code.

export const enum PricingModel {
    'AVAILABILITY',
    'DEADLINES',
    'PAYMENTS'
}

Unless I am doing the switch statement wrong... this switch statement will not work:

To fix it I propose that the generated code from JhipsterJDL be changed to generate something like this ad defined in Typescript 2.4 :

export const enum PricingModel {
    AVAILABILITY = 'AVAILABILITY',
    DEADLINES = 'DEADLINES',
    PAYMENTS ='PAYMENTS',
}
