i have question about array, for example i have an array of object, like this
const data = [
{
level: 1,
name: "Naruto",
},
{
level: 2,
name: "Dragon",
},
{
level: 2,
name: "Ball",
},
{
level: 3,
name: "Sasuke",
},
]
Now i want to create new array base on level , mean that after format it will look like this:
[
[
{
name: "naruto"
}
],
[
{
name: "Ball"
},
{ name: "Dragon" }
],
[
{name:"Sasuke"}
]
];
How can i do this, thanks you guys
I used a loop to handle your case
currentLevel - 1 is mapped with the index of the result's array
const data = [{
level: 1,
name: "Naruto",
},
{
level: 2,
name: "Dragon",
},
{
level: 2,
name: "Ball",
},
{
level: 3,
name: "Sasuke",
},
];
let result = []
for (const currentValue of data) {
const currentLevel = currentValue.level
if (!result[currentLevel - 1]) {
result[currentLevel - 1] = []
}
result[currentLevel - 1].push({
name: currentValue.name
})
}
//it's followed by index, the result will have some `undefined` if your levels have gaps. You can comment it out, if you want to keep `undefined` values
result = result.filter(item => item)
console.log({
result
})
