Javascript if - else if loop broken [closed]

a JS newbie here. Im trying to write this if else if loop in Javascript. I want it to print 'three', but it only prints two. I know something is wrong with my second else-if. Can somebody help please?

function changeNumber(value){
    number = ''
    if (value == 'one'){
        number = 'one'
    }
    else if (value = 'two'){
        number = 'two'}
    
    else if (value = 'three'){
        number = 'three'}
    
    else if (value = 'four'){
        number = "four"}   
    
    else if (value = 'five'){
        number = 'five'}
    
}

changeNumber('three');
console.log(number)
