AngularJS is well-suited for developing single page applications (SPAs) due to its features like two-way data binding, routing capabilities, and communication with servers. It allows developing SPAs that have multiple views on a single page using different URLs. Development and testing of SPAs is faster with AngularJS as it reduces the lines of code needed and provides object-oriented design. AngularJS also seamlessly integrates with other frameworks and enables easy maintenance of SPAs.
