filter
const active = data.filter((item) => item.status === "active"); const inactive = data.filter((item) => item.status === "inactive"); const nvmnghia = data.filter((item) => item.status === "nvmnghia"); const bienpm = data.filter((item) => item.status === "bienpm"); return { active, inactive, nvmnghia, bienpm };
forEach
const active = []; const inactive = []; const nvmnghia = []; const bienpm = []; data.forEach((item) => { if (item.status === "active") active.push(item); else if (item.status === "inactive") inactive.push(item); else if (item.status === "nvmnghia") nvmnghia.push(item); else if (item.status === "bienpm") bienpm.push(item); });
