In JavaScript we have the following conditional statements:
- if statement - you would use this statement to execute some code only if a specified condition is true
- if...else statement - you would use this statement to execute some code if the condition is true and another code if the condition is false
- if...else if....else statement - you would use this statement to select one of many blocks of code to be executed
- switch statement - you would use this statement to select one of many blocks of code to be executed
{
code to be executed if condition is true
}
If...else StatementUse the if....else statement to execute some code if a condition is true and another code if the condition is not true. Syntaxif (condition){
code to be executed if condition is true
}
If...else if...else StatementUse the if....else if...else statement to select one of several blocks of code to be executed. Syntaxif (condition1){
code to be executed if condition1 is true
}
else if (condition2)
{
code to be executed if condition2 is true
}
else
{
code to be executed if condition1 and condition2 are not true
}
else
{
code to be executed if condition is not true
}

Differentiate between conditional and unconditional controls in qbasic?

What are the similarities between php statement and javascript statement?
PHP and JavaScript are quite different, given that PHP is server-side and JS is (typically) client-side. However, with Node.JS -for example- you can now also use JS on the server-side. They are both interpreted languages (scripts), they are both incredibly popular languages running a huge amount of the internet, and they are both some of the simplest languages to start out in.
How do you transfer values from javascript to JSP?

What are the purpose of test condition in a loop statement in qbasic?
The purpose of using a 'test condition' inside of a loop statement/which is also called a 'conditional loop'; is to make the loop STOP counting. Otherwise, you would have gone and created what is known as being called an 'endless loop'; which just keeps on running really quite endlessly, forevermore...! To give a quick example, let's compare... CONDITIONAL LOOP EXAMPLE num% = 0 DO num% = num% + 1 PRINT num%; LOOP UNTIL num% = 3 END Output... 1 2 3 Press any key to continue... Here, when the LOOP's test condition is met: (num%=3); then, the loop stops counting up any further; the DO/LOOP block structure is broken out of; and, the final END statement will get executed. UNCONDITIONAL LOOP EXAMPLE Next, let's try re-writing the same above program; by removing the conditional statement part of the LOOP which says: (UNTIL num%=3)... num% = 0 DO num% = num% + 1 PRINT num% LOOP END Output... 1 2 3 4 5 6 7 8 9 10 11 12 .... ...because there is no conditional test statement to make the loop stop repeating itself; therefore, it just keeps on endlessly counting upwards, instead; the program never breaks out of the DO/LOOP block; and, therefore never gets to reach the final END statement. To make an 'unconditional loop' stop repeating itself inside of QBASIC IDE/Integrated Development Environment; then, use combination key press: [CTRL] + [BREAK]; and, this should make an 'endless loop' stop repeating itself any further; and, return you straight back to the Editor Screen where you can futher change/edit your code.
Php Source code for validation?
If you wish to check the syntax of your source code, you need to run the code through the PHP CLI with the -l option. There are also some online resources to validate the syntax. This will check only the syntax of your file. This will not however detect runtime errors or logic errors. You must absolutely run the script for the best possible code validation.

What is the syntax for using the conditional construct in computer programming to create a decision-making statement?
In computer programming, the syntax for using the conditional construct to create a decision-making statement typically involves the use of keywords such as "if," "else if," and "else." These keywords are followed by a condition that evaluates to either true or false, and the code block within the curly braces is executed based on the result of the condition.
