Course Delivery Methods
FITA follow many ways of course delivery methods according to the convenience of students. We provide hands-on experience and workshop classes during the training. Our classes are live online courses which are taught by real-time professionals who work in MNCs. Here we are for nearly 5 years. Our tutors with more than 8+ years of experience! We fulfil your exceptional through our training programs!
Arrow functions, Classes, asynchronous functions, variable declaration and de-structuring are some of the functions which to keep updated with the latest version. Let us see the functions added to the ES8 and there are proposed functions to be added for the ES9 version.
Dealing with the objects
The method called object values will provide the enumerable property values, returns the array and it provides the same order as provided in the loop. The function is declared with the trivial declaration.
Descriptors of a specified object
The own properties of the descriptors are defined directly and not with the object’s prototype. The returned descriptor is enumerable, configurable, get, set, value and writable.
Dealing with commas
Async function is used for the declaration of the asynchronous function. Asyn functions operate like the generators and used to return an object with async function. Translation of generator functions in case of an async function is not possible. Now we can handle the loop with await declaration.
Memory and atomics
The Unicode character is used to search the properties. The two versions of the look behind assertions are positive and negative.
Prototype called promise
If a catch is not used then the new call back will be executed. This is the function of the promising prototype.
