Let's start with the following code snippet:
let vAny: any = 10
let s1: string = vAny;
console.log(typeof s1)
In this scenario, I have explicitly defined that s1 should be a string. However, when inspecting the type of s1, it shows up as a number instead. How can this discrepancy be explained?
When utilizing TypeScript, it conducts thorough validations on the type of a certain value without incorporating any type casting.
In the scenario where vAny is defined as potentially being any kind of value, TypeScript does not verify if it is a string when assigned to s1.
If this practice was not followed...
let vAny = 10;
let s1: string = vAny;
console.log(typeof s1);
...an error message would have been generated...
Error: Type 'number' cannot be assigned to type 'string'.
...prompting the need for run-time type conversion.
let vAny = 10;
let s1: string = `${vAny}`;
console.log(typeof s1);
