Using parseInt() in TypeScript

When using angular to write something, you need to use the parseInt() method to convert the timestamp into the format of hours, minutes and seconds (xx hours-xx minutes-xx seconds), but because angular uses Typescript, and

parseInt(string:string,radix?:number):number

The first parameter passed in parseInt is of type string, so using parseInt will report an error

Parameter of type 'number' cannot be assigned to parameter of type 'string'.

I searched for a long time, and after thinking for a long time, I finally found it after I came up with a solution...

We can use the toString() method in the passed parameters to convert the passed parameters to string type

 let hours:any = parseInt(((timeSpend % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)).toString());let minutes:any = parseInt(((timeSpend % (1000 * 60 * 60)) / (1000 * 60).toString());

That's it!!!

PS: Of course, you can use Math.floor() to solve it (the first method was found on the Internet after I thought of it, and the second method was found on the Internet)
