How to write generic data types with typescript for string

Question

In my object, have different key for each of the object. for that how to write generic data type?

here is my try:

interface Dic {
    [key:string]:string; // how to write for generic values
    age:number;
}

const Object1:Dic = {
        name:"name1",
        age:0
}

const Object2:Dic = {
        village:"name1",
        age:40
}

For me it's throws the error. any one help me to understand this kind of scenarios?

You can do age:any; or [key:string]:any;.

Unfortunately in the typescript interface the dynamic property needs to be abstract enough to contain all non-dynamic properties .
