Looking for guidance on how to filter out file paths in an array that contain a specific word. How can I use the 'includes' method within an if statement?
Current code snippet:
var imagePaths = [...]
if(imagePaths.includes('index') === 'true'){
???
}
Appreciate any help!
Simply use booleans without the need for comparisons:
if (imagePaths.includes('index')) {
// The image path is present
}
or
if (!imagePaths.includes('index')) {
// The image path is not present
}
If you do choose to compare the boolean to something (not recommended), compare to true or false, not 'true' (as it is a string).
Is 'true' not equal to true?:
if (imagePaths.includes('index') === true) {
???
}
Alternatively, a more efficient approach would be to simply use the value directly, as the if statement already checks if the expression it receives is true:
if (imagePaths.includes('index')) {
???
}
If you're working with Javascript and need to create a new array based on certain conditions, it's recommended to use the array.filter method.
For example:
var imagePaths = [...];
var filteredImagePaths = imagePaths.filter(function(imagePath){
// Only include image paths that meet the criteria
return imagePath.includes('index');
});
