I want to loop through an enum to get all the values. If I have
export enum Colours{
green,
red,
blue,
brown,
purple,
black,
orange,
pink,
yellow
}
and what I want to do is
array.foreach(item => {
item.colour = Colours.value
});
So first one of the array would be green. So on so forth. Unless there is a better way of doing this?
You can use a for loop to get the index of your array and set the property of the object at that index to the enum with the same index
enum Colours{
green,
red,
blue,
brown,
purple,
black,
orange,
pink,
yellow
}
const someArray = [{name: "someThing", color: "someDefaultValue"}]
for (let i =0; i < someArray.length; i++) {
someArray[i].color = Colours[i]
}
heres a playground example
i'm just improving the @lockednlevered's answer.
If theres more entries in the array than colors, this code restarts from the 1st color and so on.
enum Colours{
green,
red,
blue
}
const enumSize = Object.keys(Colours).length / 2;
const someArray = [{name: "someThing", color: "someDefaultValue"}, {name: "someThing", color: "someDefaultValue"}, {name: "someThing", color: "someDefaultValue"}, {name: "someThing", color: "someDefaultValue"}, {name: "someThing", color: "someDefaultValue"}, {name: "someThing", color: "someDefaultValue"}]
for (let i =0; i < someArray.length; i++) {
someArray[i].color = Colours[i%enumSize]
}
console.log(someArray)
You may asking how i found the way to get the emun lenght ? On this question
