Question

我想用另一个数组覆盖一个数组。我有一个像这样的多维数组：

[[485, "Matthew"], [485, "Elizabeth"], [390, "Jayden"], [207, "Natalie"], [144, "Chloe"], [51, "Elijah"]]

我想在数组的最开头覆盖[485, "Elizabeth"]，[485, "Matthew"]来获取：

[[485, "Elizabeth"], [485, "Matthew"], [390, "Jayden"], [207, "Natalie"], [144, "Chloe"], [51, "Elijah"]]

它不一定是第一个元素，但我想根据索引选择开始覆盖的位置。

Answer 1

如果要交换数组中的某些元素，可以使用以下内容：

a = [
  [485, "Matthew"],
  [485, "Elizabeth"],
  [390, "Jayden"],
  [207, "Natalie"],
  [144, "Chloe"],
  [51, "Elijah"]
]
a[0], a[1] = a[1], a[0]

a => [[485, "Elizabeth"], [485, "Matthew"], [390, "Jayden"], [207, "Natalie"], [144, "Chloe"], [51, "Elijah"]]
