Think you could do that like this (https://code.earthengine.google.com/af976bcd1dbd1c64ec8a73f4d9aabf65):
// create an image for this example
var image = imageCollection.first()
// select boundary value, could also be zero
var value = 888.8
// create mask, gt mean greater-than, can also use lt(), lte() etc.
var mask = image.gt(2)
// create new image
var new_image = mask.multiply(value).add(image.multiply(mask.not()))
Map.addLayer(image)
Map.addLayer(new_image)
