From what Ive seen many people using jQuery which is what your example code looks like to me tend to prefix variables that contain a jQuery object with a so that they are easily identified and not mixed up with say integers.

For id selectors jQuery uses the JavaScript function documentgetElementById which is extremely efficient. If the radix parameter is omitted JavaScript assumes the following. The radix parameter is used to specify which numeral system to be used for example a radix of 16 hexadecimal indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.

The objects they identify include things such as variables functions properties events and objects. In your example it would select the element with the ID of searchTerm. It has a special meaning in JavaScript.

The addition assignment operator adds the value of the right operand to a variable and assigns the result to the variable. JavaScript operators are used to assign values compare values perform arithmetic operations and more. The objects they identify include things such as variables functions properties events and objects.

It has different values depending on where it is used. The dollar sign and the underscore _ characters are JavaScript identifiers which just means that they identify an object in the same way a name would. This is different from languages like Java where is the modulo operator.

The argument object contains a collection of the arguments used when the function was called invoked. In javascript every function receives two variables other than function parameters namely this and arguments. The sign has a number of meanings in JavaScript.

In general unlike a number of programming languages is permitted as a character in JavaScript variable names as the first character or anywhere in the middle. In this piece well look at the difference between the modulo and the remainder operator. The parseInt function parses a string and returns an integer.

It obtains the remainder between two numbers. Thats jQuery and the pound sign refers to an elements ID. The argument object contains a collection of the arguments used when the function was called invoked.

In a method this refers to the owner object. The question mark is used in JavaScript as an alternative to an if statement especially in the case where a value is assigned based on a conditional. The dollar sign and the underscore _ characters are JavaScript identifiers which just means that they identify an object in the same way a name would.

Addition or concatenation is possible. JavaScript can update and change both HTML and CSS. The types of the two operands determine the behavior of the addition assignment operator.

Its one way jQuery can select an element. So youll occasionally see thin. It applies join or any other function to the content of the template literal string.

JavaScript is the Programming Language for the Web. A in a variable means nothing special to the interpreter much like an underscore. Arithmetic operators are used to perform arithmetic between variables andor values.
