code is not complicated, but I can"t figure out why
var t = performance.now()
(function a() {
console.log(1)
setTimeout(a,100)
})() if the first line var t =. is removed, the code execution is correct. Keep the first line now, and the code will report
TypeError: performance.now (.). Is not a function is there any conflict between
performance.now () and setTimeout ? Thank you in advance ~

var t = performance.now()
;(function a() {
console.log(1)
setTimeout(a,100)
