introducing this chapter, we will explain the strategy of passing parameters to function functions in ECMAScript. In computer science, this strategy is generally called "Evaluation strategy" (Uncle Note: Some people say translation into the
The QuickStart Boolean operator (Boolean operator) is an operator that evaluates to either true or false. C # provides several very useful Boolean operators, the simplest of which is the not (negation) operator, which uses an exclamation point (!).
Classic Search Model
The information retrieval model has undergone several different stages from its birth to the present, which are based on set theory, linear algebra based, statistical and probabilistic stages. Although the expert retrieval is
In a programming language, the importance of Boolean operators is comparable to equal operators. If you do not have the ability to test two value relationships, statements such as if...else and loops will be useless.There are a total of 3 Boolean

In this chapter, we will explain the policy of passing arguments to function functions in ECMAScript.
In computer science, this strategy is commonly referred to as "evaluation strategy" (Uncle Note: Some people say that translation into
1. Logical Non-
Logic is not used! Indicates that a value of any type can be applied to the ECMAScript, and the logical non operation returns a Boolean value (True/false). The operator first converts its operand to a Boolean value, and then it is
1. Non-logical The logic is not used! It can apply any type of value with ECMAScript. A boolean value (true/false) is returned for a logical non-operation ). This operator first converts its operands to a Boolean value and then reverse it.The

For the retrieval of Boolean queries, Boolean queries refer to queries that use the And,or or not operator to concatenate terms.
