如何使用 javascript 或 lodash 返回指示 object 数组元素为空的 boolean 值

Question

I have an array of object as below.

[{key:1, value:'value1'},{key:2, value:'value2'},{key:3, value:''}]

I want to check by looping entire dynamic array and return a boolean value which indicates any of the value is empty using plain javascript and lodash. If in the array of object all value element is not empty it should return false and if any of the value is empty it should return true . Can anyone please help me to solve the same.

Use Array.some() to iterate the array, and for every object check if the value is an empty string. The method will stop and return true , as soon as such value is found. If none found, it will return false .

 const arr = [{key:1, value:'value1'},{key:2, value:'value2'},{key:3, value:''}] const result = arr.some(o => o.value === '') console.log(result)
