javascript 使用解构分配从对象分配变量

Posted 2021-05-03

// object declaration
let voxel = {
  x: 3.6,
  y: 7.4,
  z: 6.54
};

// assign values from object into same-name variables
const { x, y, z } = voxel;    // x = 3.6, y = 7.4, z = 6.54

// assign values from object into different name variables
const { x:a, y:b, z:c } = voxel;    // a = 3.6, b=7.4, c=6.54
