Vue check value is Integer: Vue.js is a progressive JavaScript framework used for building user interfaces. It provides a convenient way to check if a value is an integer by using the Number.isInteger() method. This method is a built-in JavaScript function that takes a single argument and returns true if the value passed to it is an integer, and false otherwise. It is important to note that this method does not perform any type conversion, and only considers the value passed to it as an integer if it is of the “number” type and has no fractional component. By using this method, Vue.js developers can easily validate integer inputs and perform integer-specific operations in their applications.
