Write a JavaScript program to check whether two given integer values are in the range 50..99 (inclusive). Return true if either of them falls within the range. Click me to see the solution 29. Check if Three Integers are in Range 50?99 Write a JavaScript program to check whether three ...

There are a lot of useful matchers that come with Jasmine. Later in this section, you’ll also see how to build your own. Equality: toEqual Perhaps the simplest matcher in Jasmine istoEqual. It simply checks if two things are equal (andnotnecessarily the same exact object, as you’ll ...
if (a === b) return true; // Check if 'a' and 'b' are instances of Date objects and have equal time values. if (a instanceof Date && b instanceof Date) return a.getTime() === b.getTime(); // Check if either 'a' or 'b' is null, undefined, or not an object, and ...
Data arrays are returned by most Dataview APIs that can return multiple results, such as dv.pages(). You can also explicitly convert a normal JavaScript array into a Dataview array using dv.array(<array>). If you want to convert a Data array back to a normal array, use DataArray#array...
Then you can use JavaScript's built-in equality operators. Or do you want to check that these two objects are the "same value?" If that's the case, then you'll need to do a bit more work.Here is a very basic approach to checking an object's "value equality"....
