How to convert camelcase to snake case in Javascript?
const camelToSnakeCase = str => str.replace(/[A-Z]/g, letter => `_${letter.toLowerCase()}`);
You could do something like this:
function camelToUnderscore(key) {
var result = key.replace( /([A-Z])/g, " $1" );
return result.split(' ').join('_').toLowerCase();
}
console.log(camelToUnderscore('itemName'));
Try this:
function toSnakeCase(inputString) {
return inputString.split('').map((character) => {
if (character == character.toUpperCase()) {
return '_' + character.toLowerCase();
} else {
return character;
}
})
.join('');
}
// x = item_name
