Vue3 with Typescript - this object is possibly undefined

Question

Every time I use the "this" keyword in my code, it highlights and says that "Object is possibly undefined

When you define the data property as an arrow function you should pass this as parameter like:

data:(vm)=>{//vm represents this keyword
   return{
      ....
      productType:vm.$route.path.slice(1).split("/")[0]
  }
}

Vue3 with Typescript -> this object is possibly undefined
