Here is a snippet of code I am working with:
class A {
constructor(private num: number = 1) {
}
private changeNum() {
this.num = Math.random();
}
private fn() {
if(this.num == 1) {
this.changeNum();
if(this.num == 0.5) {
// do stuff
}
}
}
}
This code defines a class 'A' with a property num and a method changeNum to modify that number.
There is also a function fn which checks if num is equal to 1, then changes it using changeNum, and checks it again.
The issue arises when TypeScript does not recognize that num has been modified through the changeNum method, resulting in the error message:
This condition will always return 'false' since the types '1' and '0.5' have no overlap.Is there a way to make TypeScript understand that num was altered by changeNum?
EDIT: I discovered that changing if(this.num == 0.5) to if(this.num == Number(0.5)) allows the program to compile correctly, but this doesn't seem like an optimal solution!
