Example
Example 1
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(arrayEvery(array1,isEven)) // Returns False
</cfscript>
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(arrayEvery(array1,isEven)) // Returns False
</cfscript>
<cfscript> array1=[1,2,3,4,5] isEven=(x)=>return x%2==0 writeOutput(arrayEvery(array1,isEven)) // Returns False </cfscript>
Example 2
<cfscript>
arrayAllEven=[2,4,6,8,10,12,14]
isEven=(x)=>return x%2==0
writeOutput(arrayEvery(arrayAllEven,isEven)) // Returns True
</cfscript>
<cfscript>
arrayAllEven=[2,4,6,8,10,12,14]
isEven=(x)=>return x%2==0
writeOutput(arrayEvery(arrayAllEven,isEven)) // Returns True
</cfscript>
<cfscript> arrayAllEven=[2,4,6,8,10,12,14] isEven=(x)=>return x%2==0 writeOutput(arrayEvery(arrayAllEven,isEven)) // Returns True </cfscript>
Example 3
<cfscript>
myarray=[2,4,6,8,10,12,14]
isGT10=(element,index,array)=>return element>10
writeoutput(arrayEvery(myarray,isGT10)) // Returns True
writeoutput(myarray.Every(isGT10)) // Returns False
</cfscript>
<cfscript>
myarray=[2,4,6,8,10,12,14]
isGT10=(element,index,array)=>return element>10
writeoutput(arrayEvery(myarray,isGT10)) // Returns True
writeoutput(myarray.Every(isGT10)) // Returns False
</cfscript>
<cfscript> myarray=[2,4,6,8,10,12,14] isGT10=(element,index,array)=>return element>10 writeoutput(arrayEvery(myarray,isGT10)) // Returns True writeoutput(myarray.Every(isGT10)) // Returns False </cfscript>
Exampe 4 - Using named parameters
<cfscript>
myarray=[2,5,8,1,4]
callback=function(element,index,array){
return element<10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns True
</cfscript>
<cfscript>
myarray=[2,5,8,1,4]
callback=function(element,index,array){
return element<10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns True
</cfscript>
<cfscript>
myarray=[2,5,8,1,4]
callback=function(element,index,array){
return element<10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns True
</cfscript>
Example 5 - Using arrow function
<cfscript>
myarray=[2,5,8,1,4,12,29]
callback=(element,index,array)=>{
return element>10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns False
</cfscript>
<cfscript>
myarray=[2,5,8,1,4,12,29]
callback=(element,index,array)=>{
return element>10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns False
</cfscript>
<cfscript>
myarray=[2,5,8,1,4,12,29]
callback=(element,index,array)=>{
return element>10
}
result=ArrayEvery(array=myarray,callback=callback)
writeOutput(result) // Returns False
</cfscript>
Member function
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(array1.Every(isEven))
</cfscript>
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(array1.Every(isEven))
</cfscript>
<cfscript> array1=[1,2,3,4,5] isEven=(x)=>return x%2==0 writeOutput(array1.Every(isEven)) </cfscript>
