Computed Property Names

Dynamic keys

Create property names dynamically:

let prop = "status"

let obj = {
  [prop]: "active",
  ["key" + 1]: "value1"
}

console.log(obj)  // { status: "active", key1: "value1" }

Square brackets around the key evaluate the expression. Use this for dynamic keys from variables or computations.
