Description
Determines if at least one element in the array satisfies a given condition.
Returns
True if at least one element matches a condition; false, otherwise.
Syntax
arraySome(array, function(item [,index, array]){} [, parallel] [, maxThreadCount])Member function
arrayObj.Some(callback)History
ColdFusion (2021 release): Introduced the following parameters:
- parallel
- maxThreadCount
ColdFusion (2018 release) Update 5: Added the function.
Parameters
Parameter | Required/Optional | Description |
array | Required | Array in which at least one element is to be searched. |
callback | Required | Function to encapsulate the criteria. |
parallel | Optional | True if you want to enable parallel programming. |
maxThreadCount | Optional | The number of threads the function can execute. The number of threads must be between 1-50. If the value exceeds 50, there is an exception. |
Example
Example 1
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(arraySome(array1,isEven)) // Returns TRUE
</cfscript>Example 2
<cfscript>
myarray=[2,4,6,8,10,12,14]
isGT10=(element,index,array)=>return element>10
writeoutput(arraySome(myarray,isGT10)) // Returns True
// Using member function
writeoutput(myarray.Some(isGT10)) // Returns True
</cfscript>Example 3 - Using named parameters
<cfscript>
myarray=[2,5,8,1,4]
callback=function(element,index,array){
return element>10
}
result=ArraySome(array=myarray,callback=callback)
writeOutput(result) // Returns False
</cfscript>Example 4 - Using arrow function
<cfscript>
myarray=[2,5,8,1,4]
callback=(element,index,array)=>{
return element<10
}
result=ArraySome(array=myarray,callback=callback)
writeOutput(result) // Returns True
</cfscript>Member function
<cfscript>
array1=[1,2,3,4,5]
isEven=(x)=>return x%2==0
writeOutput(array1.Some(isEven))
</cfscript>Using parallelization
<cfscript>
for(i=1;i<=10000;i++){
if(i == 4500){
arr[i]=0;
}
else
arr[i]=i*2;
}
result = arr.some(function(item){
if (item Mod 2 == 0)
return false
return true
},true,20)
writeoutput(result)
</cfscript>
