Brackets Key Javascript at Lillie Authement blog

Brackets Key Javascript. Bracket notation enables a developer to access an object’s properties in javascript. It's the new es2015 (the ecmascript spec formally known as es6) computed property name syntax. We have also learned that a map datastructure maps keys to values. Also, you should put into consideration. We had a first glance at how algorithm performance is described using. The detailed breakdown of each. An object is a collection of properties, and a property is an association between a name (or key) and a value. We can use keys to directly look up values in a map which we implement using an object. It is an alternative to the more common dot notation. That value serves as a key for accessing. When dealing with a static key, dot notation is most efficient and when dealing with dynamic keys, the bracket notation should be used. We learned how we can dynamically look up values of property by using variables with square bracket notation; The bracket notation approach involves using square brackets, in which you have an expression that evaluates to a value. Bracket notation offers more flexibility than dot notation.
