Function isObjectLike

  • Checks if the given value is object-like.

    A value is object-like if its type is object and it is not null.

    This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to an object-like value.

    true if the value is an object-like, false otherwise.

    const value1 = { a: 1 };
    const value2 = [1, 2, 3];
    const value3 = 'abc';
    const value4 = () => {};
    const value5 = null;

    console.log(isObjectLike(value1)); // true
    console.log(isObjectLike(value2)); // true
    console.log(isObjectLike(value3)); // false
    console.log(isObjectLike(value4)); // false
    console.log(isObjectLike(value5)); // false
