How to stop error reporting in TypeScript?

// this will ignore the code that is one line below

// @ts-ignore

const myAge : number = “25” // no typescript error

const isTrue : boolean = 4; // error

// this will ignore checking the entire file, must be at its top

// @ts-nocheck

const myAge : number = “25” // no error

const isTrue : boolean = 4; // no error
// @ts-expect-error

console.log(47 * “octopus”); //This line will cause an error and TS won’t disturb you because you are using “ts-expect-error” for nothing.
// @ts-expect-error

console.log(1 + 1); //However, here the log() function will output 2, which will not throw an error. Thus, there’s no purpose of using “ts-expect-error”.
