JavaScript: Check whether a value is object-like also check whether the provided value is not null and its typeof is equal to 'object'

JavaScript fundamental (ES6 Syntax): Exercise-193 with Solution

Check If Object-Like

Write a JavaScript program to check whether a value is object-like. Check whether the provided value is not null and its typeof is equal to 'object'.

• Check if the provided value is not null and its typeof is equal to 'object'.

Sample Solution:

JavaScript Code:

// Define a function 'isObjectLike' that checks if the given value 'val' is object-like
const isObjectLike = val =>
  // Check if 'val' is not null and its type is 'object'
  val !== null && typeof val === 'object';

// Test cases to check if the values are object-like
console.log(isObjectLike({}));          
console.log(isObjectLike([1, 2, 3]));    
console.log(isObjectLike(x => x));      
console.log(isObjectLike(null));

Output:

true
true
false
false
