how to use a variable value as a property in an JS object

Question

in JS I would like to use a variable value as a property in an object. for example:

    let myVar='toto';   
    let myObjet={
             toto:['1', '2','3'],
             tata: ['a','b','c']
    }
//I want to recover the array of toto property ['1', '2','3']

let myArray=myObjet.myVar

but myObjet.myVar does not work.

how to use the value of myVar?

Answer 1

you can enter the object like this:

console.log(myObjet[myVar])
