Filter an array of objects by the length of the value of a string

Question

want to filter an array of objects by array value of a key.

 var data = [ { "name": "Jim", "age" : [] }, { "name": "Jerry", "age": [1,2] } ]; var notEmpty = _.filter(data, ['age', null]); 

would like to have the output of variable notEmpty return the object Jerry since the age array is not empty.

Answer 1

如果没有lodash，它将是：

  const notEmpty = data.filter(el => el.age.length);

Answer 2

使用香草javascript，这将给您所需的结果：

data.filter(x => x["age"].length > 0)
