Yes c/c++ goto It's internal

let i = 0
let j = 0
out: for (i = 0; i < 3; i++) {
  console.log("i", i, j)
  for (j = 0; j < 3; j++) {
    console.log("j", i, j)
    if (j === 1) {
    //   break
      break out;
    }
  }
}
console.log("end")
/*
i 0 0
j 0 0
j 0 1
i 1 1
j 1 0
j 1 1
i 2 1
j 2 0
j 2 1
