use variable for object key javascript code example
Example 1: javascript for key in object
// iterates over all enumerable properties of an object that are
// keyed by strings (ignoring ones keyed by Symbols),
// including inherited enumerable properties.
const object = { a: 1, b: 2, c: 3 };
for (const property in object) {
console.log(`${property}: ${object[property]}`);
}
// expected output:
// "a: 1"
// "b: 2"
// "c: 3"
Example 2: javascript create object key from variable
//For ES6 and Babel
{
[yourKeyVariable]: "yourValue",
}
// ES5 Alternative
// Create the object first, then use [] to set your variable as a key
var yourObject = {};
yourObject[yourKeyVariable] = "yourValue";
