Stack Overflow works best with JavaScript enabled.JavaScript is the most widely used scripting language on earth. Here are some examples of key syntax patterns in JavaScript. The arguments object is an array-like object in that the structure of the object is similar to that of an array; however it should not be considered an array as it has all the functionality of an object that stores all of the arguments that you passed to a function and is proprietary to that function in particular.

If you were to pass 3 arguments to a function, say storeNamesthose 3 arguments would be stored inside an object called arguments and it would look like this when we pass the arguments storeNames "Mulder", "Scully", "Alex Krycek" to our function:.

You can invoke arguments by using arguments[n] where n is the index of the argument in the array-like object. But if you want to use it as an array for iteration purposes or applying array methods to it, you need to convert it to an array by declaring a variable and using the Array. Since slice has two the parameter end is optional parameters. You can grab a certain portion of the arguments by specifying the beginning and the ending of your portion using the slice.

Sorry, you need to enable JavaScript to visit this website.

Check out the following code:. Important : You should not slice on arguments because it prevents optimizations in JavaScript engines V8 for example.

Instead, try constructing a new array by iterating through the arguments object. So, what other method is available to convert arguments to an array? I recommend the for-loop not the for-in loop. You can do it like this:. For more information on the optimization issues: Optimization Killers: Managing Arguments. Say we have the following function non-ES6 :.

The rest parameter must always come as the last argument in your function definition. The operators are for addition, subtraction, multiplication, division and remainder, respectively. Hint: When making calculations it is possible to use parentheses to prioritize which numbers should be multiplied together.

Important: As you can see, you cannot perform any sort of operations on Infinity. Arrow functions are a new ES6 syntax for writing JavaScript function expressions. The shorter syntax saves time, as well as simplifying the function scope.

You no longer need the function and return keywords, or even the curly brackets. Before arrow functions, new functions defined their own this value. To use this inside a traditional function expression, we have to write a workaround like so:. Assignment operators, as the name suggests, assign or re-assign values to a variable. While there are quite a few variations on the assignment operators, they all build off of the basic assignment operator. The other assignment operators are a shorthand for performing some operation using the variable indicated by x above and value indicated by y above and then assigning the result to the variable itself.

This is the same as applying the addition operator and reassigning the sum to the original variable that is, xwhich can be expressed by the following code:.

To illustrate this using actual values, here is another example of using the addition assignment operator:. Booleans are a primitive datatype commonly used in computer programming languages. By definition, a boolean has two possible values: true or false. In JavaScript, there is often implicit type coercion to boolean. If for example you have an if statement which checks a certain expression, that expression will be coerced to a boolean:.

All other values will be coerced to true. As you can see, the or operator checks the first operand. There is also a native JavaScript Boolean object that wraps around a value and converts the first parameter to a boolean value.

If a value is omitted or falsy —0, -0, nullfalseNaNundefinedor an empty string "" — the object's value is false. Pass all other values, including the string "false"and the object's value is set to true. Note that primitive Boolean values true and false are different than those of the Boolean object.Wind Chill is a mysterious and often misunderstood phenomenon.

In JavaScript, there are three main ways in which any value can be converted to a string. This blog post explains each way, along with its advantages and disadvantages.

Three approaches for converting to string The three approaches for converting to string are: value. That leaves us with approaches 2 and 3, which are basically equivalent. But that is a matter of taste, some people prefer this approach to String value.

String value : This approach is nicely explicit: Apply the function String to value. The only problem is that this function call will confuse some people, especially those coming from Java, because String is also a constructor. The constructor produces an instance of the type String an object. The latter is hardly ever useful in JavaScript, which is why you can usually forget about String as a constructor and concentrate on its role as converting to string.

But how do they actually do that? It turns out that they do it in slightly different ways, but usually arrive at the same result. Converting a primitives to string Both approaches use the internal ToString operation to convert primitives to string. The following table explains how ToString operates on primitives. Argument Result undefined "undefined" null "null" boolean value either "true" or "false" number value the number as a string, e.

ToPrimitive Number : To convert an object obj to a primitive, invoke obj. If the result is primitive, return that result. Otherwise, invoke obj. Otherwise, throw a TypeError. ToPrimitive String : Works the same, but invokes obj. Here is why: Most objects use the default implementation of valueOf which returns this for objects. If, however, an object is an instance of BooleanNumber or Stringthen valueOf will return a primitive the one wrapped by the object.

That means that the two operations now compute their results as follows: ToPrimitive Number returns the result of applying ToString to the result of valueOf the wrapped primitive. ToPrimitive String returns the result of toString the result of applying ToString to the wrapped primitive. Thus, they both still arrive at the same destination, but by a different route. Conclusion Which of the three approaches for converting to string should you choose?

Which one people prefer is a matter of taste.
