break

Baseline Widely available

This feature is well established and works across many devices and browser versions. Its been available across browsers since julio de 2015.

Resumen

Termina el bucle actual, sentecia switch o label y transfiere el control del programa a la siguiente sentencia a la sentecia de terminacin de stos elementos.

In this article

Sintaxis

break [etiqueta];
etiqueta

Identificador asociado con la etiqueta de la sentencia.

Descripcin

La sentencia break incluye una etiqueta opcional que permite al programa salir de una sentencia etiquetada. La sentencia break necesita estar anidada dentro de la sentencia etiquetada. La sentencia etiquetada puede ser cualquier tipo de sentencia; no tiene que ser una sentencia de bucle.

Ejemplos

Ejemplo: Usando break

La siguiente funcin tiene una sentencia que termina el bucle while cuando i es 3, y entonces devuelve el valor 3 * x.

js
function comprobarBreak(x) {
  var i = 0;
  while (i < 6) {
    if (i == 3) break;
    i++;
  }
  return i * x;
}
