删除或过滤嵌套数组中的 object (Javascript)

Question

Based on an array like this:

 var p = [
           {x: [
                 {x1: 1}, 
                 {x1: 2},
               ]
           },
         ];

How can I get something like this:

// Result of filtering an object where key is 'x1' and value is greater than 1
p === [
        {x: [
              {x1: 2},
            ]
        },
      ];

Answer 1

p = p.map(v => {
    v.x = v.x.filter(({ x1 }) => x1 > 1)
    return v
})

or (shorter syntax)

p = p.map(v => (v.x = v.x.filter(({ x1 }) => x1 > 1), v))

Answer 2

to create a new array q with the desired properties

var q = [
    {x: p[0].x.filter( (x) => x.x1 > 1 ) }
]

or if you wish to change the array p in place

p[0].x = p[0].x.filter( (x) => x.x1 > 1 )

Answer 3

This code will return an array of objects with property 'x1' greater than 1.

 var p = [{x: [{x1: 1}, {x1: 2}]}]; let filtered = p.map(obj => obj.x.filter(y => y.x1 > 1)); console.log(filtered);

Answer 4

var result = p[0].x.find(x = x.x1 > 1)

Answer 5

use map and filter

 var p = [ {x: [{x1: 1}, {x1: 2}]}, ]; result=p.map((o)=>({...oxfilter(y=>y.x1>1)})) console.log(result)
