Set the default value to the jmeter local variable same as the property variable

Question

We can set the default value for property variable ${__P(Threads,1)}, if Threads is null then the default value 1 will be used.

Now I want to use the variable in the same way.

We can call the variable as ${name} in JMeter and if this name is null then the default variable should come into action.

I don't want to use preprocessors need in format of function same as property variable.

Answer 1

The closest equivalent would be __V() function:

${__V(name,default value)}

Alternatively you can declare the initial values of the JMeter Variables using i.e. User Defined Variables configuration element like:
