Return searchInArray(Object. Return (text.toString().indexOf(keyword) != -1) But apparently the code is not optimized as it takes some time to execute the function, and it is subject to client PC processing power. This way of accessing values is one of my personal favorites as it remains highly readable and DRY, even if the object is deeply nested.I wrote code to search by keyword, and it will check all of the values from the object property, including an array in the object. However, when dynamically setting values in a nested object (when you dont know exactly what the name of the key is going to be), you have to use the bracket notation.

Replace nested property for an interview. i can't use : Object.values (object).every (i > (i null i '')) It return False since the nested object still consider as a different value than 0 and null. Test if a key-value pair exists in nested object in Typescript. i need to check every single values in it is 0 or null, return true if all values is either 0 or null, false if any of the values different than null or 0. Iterating through nested array of objects. Static helper function to set a property on another object. Instead of using the & operator to check for null/undefined values, we use the || operator and an empty object literal. Its illegal to pass an object as a child of a component. Rewriting clumsy code that gets the value of a nested property in JS object. This method of accessing values is similar to what was described in the above point. Use JSON.stringify (jsonObject) to convert JSON Object to. To write a JSON Object to a local file, following is a step-by-step guide : Stringify JSON Object. Is there a better way in mongoose to set certain values in an array but.
