What could be the reason for the variable's type being undefined in typescript?

After declaring the data type of a variable in TypeScript and checking its type, it may show as undefined if not initialized. For example:

var a:number;
console.log(a);

However, if you initialize the variable with some data, then the type will be displayed correctly as number. This is because TypeScript relies on explicit initialization to infer types accurately.
