检查 JavaScript Object 中是否存在值

Question

Learning JSX here and I was wondering if theres a way to check if a value appears in a object in JavaScript

ie We have an obj : anObj ={ myFoo: "MONDAY;TUESDAY;WEDNESDAY" }

How could I check if monday etc appears in this object?

Answer 1

You can find the value in Object.values with.includes()

let valueExists = Object.values(obj).includes("value you looking for");

Answer 2

You can check in the values array

const valuesArray=Object.values(anyObj);
console.log(valuesArray.some((value)=>value.includes('monday'))
