What is the principle of using unsigned right shift to determine whether this value is a number?

1 >>> 0 // 1
undefined >>> 0 // 0
null >>> 0 // 0
"string" >>> 0 // 0

as mentioned in the question, why did you produce this result? Is it because of the mechanism of js? will he first change the value on the right to number before moving to the right?

Is

the same effect as this symbol?
