Declare imageNames with var, use .format() instead of %, remove tab before closing bracket
## Code Before:
import os

if __name__ == '__main__':
	js_file = open('cropList.js', 'w')
	js_file.write('imageNames = [\n')
	js_file.write(',\n'.join(['\t"%s"' % name for name in os.listdir('originals')
		if name[-4:] in ('.JPG', '.jpg', '.PNG', '.png')]))
	js_file.write('\n\t];\n')
	js_file.close()

## Instruction:
Declare imageNames with var, use .format() instead of %, remove tab before closing bracket
## Code After:
import os

if __name__ == '__main__':
	js_file = open('cropList.js', 'w')
	js_file.write('var imageNames = [\n')
	js_file.write(',\n'.join(['\t"{}"'.format(name) for name in os.listdir('originals')

	js_file.write('\n];\n')
	js_file.close()
