Hello I was trying to store some data in my array and I did try allData.push(Data1, Data2, Data3) but it said .push was not a function and it also didn't let me just allData(Data1, Data2, Data3), w/e data I get it overrides the previous one. I also tried allData(Data1 Data2 Data3)

This is my code:

useEffect(() => {
    let x = 0;
    
    LibrosID1.map((i) => {
      x  = i.precio
    })

    LibrosID2.map((i) => {
      x  = i.precio
    })

    LibrosID3.map((i) => {
      x  = i.precio
    })

    setAllItems(LibrosID1, LibrosID2, LibrosID3)
    setSubTotal(parseFloat(x).toFixed(2))

  });

// I have 3 like this the only thing that changes is variable # from 1 to 3

const [LibrosID1, setLibrosID1] = useState([]);
    const handleChange1 = (e, data) => {
    const { name, checked } = e.target;
    if (checked) {
      // if cheked and selectall checkbox add all fileds to selectedList
      if (name === "allSelectNuevos") {
        setLibrosID1(librosNuevos);

        let x = 0
        librosNuevos.map((i) => {
          x  = i.precio
          setTPLibrosNuevos(parseFloat(x).toFixed(2))
        })

      } else {
        // if cheked and specific checkbox add specific field to selectedList
        setLibrosID1([...LibrosID1, data]);

        let x = 0
        LibrosID1.map((i) => {
          x  = i.precio
          setTPLibrosNuevos(parseFloat(x).toFixed(2))
        })
      }
    } else {
      // if uncheked and selectall checkbox add remove all fileds from selectedList
      if (name === "allSelectNuevos") {
        setLibrosID1([]);

        let x = 0
        librosNuevos.map((i) => {
          x = 0
          setTPLibrosNuevos(parseFloat(x).toFixed(2))
        })

      } else {
        // if uncheked and specific checkbox remove specific field from selectedList
        let tempuser = LibrosID1.filter((item) => item.id !== data.id);
        setLibrosID1(tempuser);

        let x = 0
        tempuser.map((i) => {
          x  = i.precio
          setTPLibrosNuevos(parseFloat(x).toFixed(2))
        })
      }
    }
  };

  useEffect(() => {
    console.log(LibrosID3, tpPaqueteCuadernos, allItems);
 }, [LibrosID1, tpLibrosNuevos])

In short I'm calculating my subtotal and that bit is working and now I want to store all the items I'm "buying" in allItems

This is what it prints when I click on the LibrosID1 all checkbox:

This is what it prints when I click on the LibrosID2 all checkbox:

And finally this is when I click on the last one LibrosID3 all checkbox:

As you can see it only adds the value from LibrosID1 even though I have it as setAllItems(LibrosID1, LibrosID2, LibrosID3)

Any tips, documentation and help is welcome.

By looking at your code, I assume setAllItems should be storing the array. To do that you need to pass an array to setAllItems like setAllItems([LibrosID1, LibrosID2, LibrosID3])
