To set the lengt harray property to the value . Both of these actions will result in an empty array. Metoda nr let arr 'hello' 'world' arr console. log arr Metoda nr const arr 'hello' 'world' arr .length console.log arr What is the ternary operator used for Truth be told the name ternary operator during a technical interview wouldn't mean much to me. In such a situation it is worth asking to paraphrase the question instead of answering "I don't know" . A paraphrased question might be what are some ways you know to write a conditional statement in code.
The ternary operator is an alternative way of writing a conditional statement without using the keyword if. An expression with this operator is constructed by specifying the Phone Number List value to be checked followed by a question mark. It is followed by the code that will be executed when the condition is met. Then we add a colon followed by the code to be executed when the condition is not met. The following example illustrates the use of the ternary operator . const arr 'hello' arr includes 'hello' console.log true console.log false arr. includes 'world' console.
Log true console.log false Write a function that accepts a string of characters a sentence and a string of characters with the word order reversed. Example for "Ala has a cat" the function should return "Ala has a cat" The aim of this task is to test your knowledge of the basic functions and mechanisms of the JavaScript language. The first function used is split . The split function will divide the string into individual words and place each word as a separate element in the array. This function takes as a parameter string which will be used to separate elements in our case it will be a space.
